Description

A kind of measuring method of length of dry sand of tailings reservoir and measuring system
Technical field
The present invention relates to safety technique field, mine tailing storehouse, relate in particular to a kind of measuring method and measuring system of length of dry sand of tailings reservoir.
Background technology
The mine tailing storehouse refers to build a dam, and the interception mouth of a valley or exclosure constitute, in order to store up the place of the waste residue of discharging (for example: waste residue generates electricity) in institute's mine tailing of discharging after the ore dressing or other commercial production; It is an artificial rubble flow dangerous matter sources with high potential energy, has dam break danger, and it is imperative therefore safety monitoring to be carried out in the mine tailing storehouse.
Mainly (tailing dam comprises initial dam and fill dam two parts by tailing dam in the mine tailing storehouse; Initial dam refers to be used as in the capital construction dam that supports later stage tailings impoundment body; Fill dam refers in the production run that dam crest above the heap with the mine tailing filling in dam built the dam that forms in the early stage) tackle solid mine tailing and water in the mine tailing ore pulp.Along with the discharging gradually of mine tailing ore pulp, the water in the mine tailing ore pulp sinks to converging gradually, and the interception face at tailing dam forms lithosomic body to the solid mine tailing in the mine tailing ore pulp owing to be subjected to hydraulic impact.In safety technique field, mine tailing storehouse, surface and partly be commonly called deposition beach or dried beach in the top layer of this lithosomic body; The peak of doing the beach is positioned at the intersection of doing beach and the outer slope of tailing dam, is commonly called the top, beach herein; The beach of doing the beach is pushed up to the mine tailing storehouse the horizontal range between the flowage line and is commonly called and does beach length.Do beach length and be and weigh the whether important indicator of safe operation of mine tailing storehouse, may cause water level in the storehouse in and overflow security incidents such as top, the dam break of mine tailing storehouse if exceed standard, so must monitor the dried beach length in mine tailing storehouse.
At present, the method that the dried beach length in mine tailing storehouse is measured mainly comprises optical image recognition method, laser broken line deduction method and gradient predication method.Wherein, optical image recognition method and laser broken line deduction method are subjected to the influence of weather conditions and light condition very serious, under the lower situation of visibility such as strong wind sand, dense fog, heavy rain or night, camera can't get access to the picture rich in detail in mine tailing storehouse, the reflection strength of laser bright line also can be had a strong impact on, therefore these two kinds of methods measuring accuracy at this moment is extremely low, even can't finish measurement; Simultaneously, because near the dried beach the flowage line also is in dampness usually, under cold climate, the phenomenon of freezing also can appear in the surface, dried beach of these positions, therefore the accurate position of flowage line can't be determined substantially by image recognition or the irreflexive mode of laser, and then also just measurement can't be finished; In addition, for doing beach length for the mine tailing storehouse of the supreme kms of hundreds of rice, existing imageing sensor (for example: charge coupled cell ccd sensor, complementary metal oxide semiconductor (CMOS) cmos sensor etc.) all can't reach sufficiently high measuring accuracy in so big range, so these two kinds of methods also can't normally be measured in this case.
Be illustrated in figure 1 as the principle schematic of gradient predication method in the prior art, its specific implementation is: choose two monitoring points on the dried beach in mine tailing storehouse, wherein first monitoring point is arranged near the top, beach of doing beach and tailing dam P1 handing-over, second monitoring point is arranged on the direction of flowage line P2 in beach top to the storehouse, and the horizontal range that push up on second monitoring point and beach equals minimum dry beach length; Respectively bury a monitoring rod P4 underground two monitoring points, and the top of every monitoring rod P4 all is equipped with a level meter P5, determines the absolute altitude of each level meter P5 and the relative distance between two level meter P5 in advance; A level meter P5 is fixed at top at the flood discharge well P3 of mine tailing library postlude, and determines the absolute altitude of this level meter P5 in advance.When length of dry sand of tailings reservoir being measured, the level meter P5 by two monitoring points can record place, two monitoring points and do the surface, beach to the relative distance of level meter P5, uses geometric knowledge of the prior art to calculate again and does the beach gradient at every turn; Level meter P5 by flood discharge well P3 top can calculate water level in the outbound, just can calculate dried beach length according to water level in the storehouse and the dried beach gradient again.
But there is following shortcoming at least in above-mentioned gradient predication method:
(1) because the ore drawing amount is uncertain in the mine tailing storehouse at every turn, and then make the beach face deposition process on deposition beach irregular, therefore depositing the beach is not a smooth inclined-plane, but has the curved surface that rises and falls; Simultaneously, along with the continuous deposition of mine tailing in the mine tailing ore pulp, the gradient on deposition beach also presents a curve that constantly changes; Only rely on two check points just to determine the way of doing beach length in the existing gradient predication method, be that smooth inclined-plane and deposition beach gradient amplification do not become prerequisite to deposit the beach, therefore there is very large deviation in the existing measured length of dry sand of tailings reservoir of gradient predication method, can not true and accurate reflects the actual security situation in mine tailing storehouse.
(2) because the area of dry sand of tailings reservoir is wide, do the surface, beach according to existing gradient predication method and need set up a lot of monitoring rods, and most apart from each other between the monitoring rod, so the absolute altitude of the level meter at monitoring rod top need be selected a stable lofty perch usually, and (for example: the high mountain mountain top) as the mapping reference point, the transmission of recycling coordinate is determined; But it is lower generally to survey and draw the reference point accuracy class, and then make the coordinate system of each measuring system in the mine tailing storehouse not closed, therefore can there be certain measuring error in the absolute altitude of the level meter that records, this will make the measurement of length of dry sand of tailings reservoir very mistake occur, can't accurately reflect the actual safety case in mine tailing storehouse.
(3) to form the deposition beach be soft state to mine tailing, after monitoring rod is imbedded wherein, can produce depression or inclination owing to the weight of own wt and level meter, and then make measurement result serious deviation occur; Simultaneously, along with the mine tailing that deposits the beach increases gradually, monitoring rod can be buried gradually and can't be reclaimed; Therefore existing gradient predication method needs the interim monitoring rod of burying costliness again underground.
(4) owing to all contain the aggressivity material mostly in the mine tailing, therefore in existing gradient predication method, the service cable of level meter and the communications cable are if take buried mode can be subjected to very strong corrosion, and serviceable life is extremely short; If adopt built on stilts system of laying that service cable and the communications cable are set, then exist again thunderbolt, electric pole tilt, with serious problems such as dried beach lifting electric pole are buried.

Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the invention, the technical scheme in the embodiment of the invention is clearly and completely described, obviously, described embodiment only is the present invention's part embodiment, rather than whole embodiment.Based on embodiments of the invention, those of ordinary skills belong to protection scope of the present invention not making the every other embodiment that obtains under the creative work prerequisite.
At first need to prove, need long time owing to do the deposition on beach, the variation of therefore doing surface, beach global shape is a gradual process; In actual applications, the discharging of mine tailing ore pulp in the mine tailing storehouse is to have special technician to be responsible for adjusting, its discharge process can take into full account the lifting speed of doing beach integral body, therefore in one period long period, the variation of doing the surface, beach is similar to can regard a constant height lifting process of dried beach surface global shape as; But this height lifting process is not the lifting process of each point rising height unanimity, but the lifting process that is diminished gradually to top, beach rising height by flowage line, the absolute altitude on top, beach does not almost change in the period at this section.The measuring method of the length of dry sand of tailings reservoir that the embodiment of the invention provides and measuring system have been considered to propose after these characteristics in mine tailing storehouse just; To describe the present invention from measuring method and two aspects of measuring system respectively below.
(1) a kind of measuring method of length of dry sand of tailings reservoir
As shown in Figure 2, a kind of measuring method of length of dry sand of tailings reservoir, it specifically can comprise the steps:
Step 1, selectedly in the mine tailing storehouse do beach monitoring section (the so-called beach monitoring section of doing refers to make straight line from top, tailing dam beach to the direction of flowage line, as profile line tailing dam and Gan Tan are carried out vertical profile with this straight line, resulting section is exactly to do beach monitoring section), and at least 3 monitoring points and at least 5 auxiliary sighting points are chosen in the surface, dried beach of monitoring the section place on this dried beach.
Wherein, in the monitoring point, monitoring site in the flowage line distance less than 5 meters the water surface on, this monitoring point is the flowage line monitoring point; All the other monitoring points are dried beach face monitoring point, and dried beach face monitoring point equidistantly is distributed between top, beach and the flowage line; In auxiliary sighting point, the distance on auxiliary sighting point and top, beach is less than 3 meters, and this auxiliary sighting point is top, beach auxiliary sighting point; All the other auxiliary sighting points equidistantly are distributed between top, beach and the flowage line.
Particularly, the technical scheme of choosing monitoring point and auxiliary sighting point on the surface, dried beach at this dried beach monitoring section place can comprise: adopt prior art to record the length on this monitoring Gan Tan inclined-plane, section place, dried beach, the length on inclined-plane, some beaches is less than or equal to 100 meters, then choose 3 monitoring points and 5 auxiliary sighting points on the surface, dried beach at this dried beach monitoring section place, and the monitoring point except the flowage line monitoring point equidistantly is distributed between top, beach and the flowage line, and the auxiliary sighting point except dried beach face monitoring point equidistantly is distributed between top, beach and the flowage line; The length on inclined-plane, some beaches is greater than 100 meters, then the every increase of the length on Gan Tan inclined-plane just increases 1 monitoring point and 2 auxiliary sighting points newly for 50 meters, and the monitoring point except the flowage line monitoring point equidistantly is distributed between top, beach and the flowage line, and the auxiliary sighting point except dried beach face monitoring point equidistantly is distributed between top, beach and the flowage line.
Further, in the mine tailing storehouse, can arbitrarily select one or more dried beach monitoring sections, also can which determine to select do beach monitoring section according to the scale in mine tailing storehouse, the mine tailing storehouse concrete conditions such as profile of tailing dam, but preferably select to reflect the dried beach monitoring section of mine tailing storehouse safety case; In actual applications, can do beach monitoring section according at least a the selecting in the following technical scheme:
(1) obtain in tailing dam and the mine tailing storehouse the shortest line segment of distance between the flowage line, and this line segment is carried out vertical profile as profile line to tailing dam and Gan Tan, resulting section is as dried beach monitoring section selected in the mine tailing storehouse;
(2) obtain the profile of flowage line in the profile of tailing dam and the mine tailing storehouse, and point nearest apart from this kink on the kink of the profile of tailing dam and the flowage line is connected with straight line, as profile line tailing dam and Gan Tan are carried out vertical profile with this straight line again, resulting section is as dried beach monitoring section selected in the mine tailing storehouse;
(3) obtain the profile of flowage line in the profile of tailing dam and the mine tailing storehouse, and point nearest apart from this kink on the kink of the profile of flowage line and the tailing dam is connected with straight line, as profile line tailing dam and Gan Tan are carried out vertical profile with this straight line again, resulting section is as dried beach monitoring section selected in the mine tailing storehouse;
" in tailing dam and the mine tailing storehouse between the flowage line the shortest line segment of distance " described in above-mentioned three kinds of schemes, " profile of tailing dam " and " profile of the flowage line mine tailing storehouse in " can be adopted optical image recognition method of the prior art or laser broken line deduction method to calculate under the good situation of light and weather conditions and be drawn, also can adopt other feasible methods of the prior art to calculate; And " on the flowage line point " nearest apart from tailing dam profile kink and " on the tailing dam point " nearest apart from flowage line profile kink can utilize the geometry analysis method of prior art to calculate, and also can adopt other feasible methods of the prior art to calculate; Because these all are prior aries, so repeat no more in the present specification.
Need to prove in this step, in the mine tailing storehouse, should select a dried beach monitoring section at least, and each dried beach monitoring section is all carried out according to the step 1 that provides in the example of the present invention to step 5, thereby determine the dried beach length at each dried beach monitoring section place, so that reflect the actual safety case of this dry sand of tailings reservoir more truely and accurately.Apparently, the quantity of selected dried beach monitoring section is more many in the mine tailing storehouse, the actual safety case that just more can truly accurately reflect dry sand of tailings reservoir, if but selected dried beach monitoring section is too much, will significantly increase the monitoring cost so, therefore selected doing also should be considered actual monitoring cost when section is monitored on the beach in the mine tailing storehouse.
Step 2, obtain the absolute altitude of each monitoring point of initial time and the absolute altitude of each auxiliary sighting point, and simulate the dried beach surface curve equation that initial time should be done monitoring section place, beach according to the absolute altitude of each monitoring point of initial time and the absolute altitude of each auxiliary sighting point.
Particularly, directly utilize total powerstation to record the absolute altitude of each monitoring point of initial time and the absolute altitude of each auxiliary sighting point, the software (for example: EXCEL of the prior art, ORIGIN science are calculated and mapping software) that possesses curve match function in the recycling prior art is handled the absolute altitude of each monitoring point and the absolute altitude of each auxiliary sighting point, should do the initial curve equation on surface, beach in dried beach monitoring section place thereby obtain initial time.Should do monitoring section place, beach dried beach surface curve The Representation Equation be to do the absolute altitude of certain point on the surface, beach and this point to the funtcional relationship of top, beach horizontal range.
Step 3, when the dried beach length at this dried beach monitoring section place being measured at every turn, obtain the absolute altitude of each monitoring point of current time in real time, and according to the absolute altitude of each monitoring point of initial time, the absolute altitude of each monitoring point of current time, and this dried beach surface curve equation of doing monitoring section place, beach of initial time is determined each dried beach face monitoring point far from the current measuring error of top, beach horizontal range.
Wherein, in the absolute altitude of each monitoring point of current time, the absolute altitude of flowage line monitoring point is current time water level absolute altitude.
Particularly, the described absolute altitude that obtains each monitoring point of current time in real time can comprise: before the dried beach length at dried beach monitoring section place is measured to this first, (this dried beach monitoring device can adopt structure as shown in Figure 3 respectively to bury a dried beach monitoring device underground in each monitoring point, measuring system hereinafter partly has description, does not therefore give unnecessary details herein); The beach monitoring device be should do and target Q3, level meter P5 and connecting link Q2 comprised; Connecting link Q2 vertically imbeds in the dried beach at place, monitoring point; Level meter P5 and target Q3 all are fixed on the top of connecting link Q2; When the dried beach length at this dried beach monitoring section place being measured at every turn, (for example: this hi-Fix observation device can be intelligent total powerstation by the hi-Fix observation device, it can record the absolute altitude of specifying target Q3 on the monitoring point automatically by programmed control, thereby can accurately record the absolute altitude of target Q3 on each monitoring point in real time, to prevent doing beach monitoring device depression or inclination causes measuring error) record the absolute altitude of target Q3 on each monitoring point, and according to the absolute altitude of target Q3 on each monitoring point, and default target Q3 and the distance between the level meter P5 absolute altitude of determining level meter P5 on each monitoring point; For each monitoring point, record the surface, dried beach at this place, monitoring point to the relative distance between the level meter P5 by the level meter P5 on the monitoring point; Again according to the absolute altitude of level meter P5 on each monitoring point, and surface, dried beach to the relative distance between the level meter P5 is determined the absolute altitude on the surface, dried beach of each monitoring point, the i.e. absolute altitude of each monitoring point.
Further, according to the absolute altitude of each monitoring point of initial time, the absolute altitude of each monitoring point of current time, and the initial time dried beach surface curve equation that should do monitoring section place, beach is determined each dried beach face monitoring point and can be comprised the steps: far from the current measuring error of top, beach horizontal range
Step 31, the absolute altitude substitution initial time of each dried beach face monitoring point in the absolute altitude of each monitoring point of initial time should be done the dried beach surface curve equation at monitoring section place, beach, obtain the horizontal range that push up on each dried beach face monitoring point of initial time and beach;
Step 32, the absolute altitude substitution initial time of each dried beach face monitoring point in the absolute altitude of each monitoring point of current time should be done the dried beach surface curve equation at monitoring section place, beach, obtain the horizontal range that push up on each dried beach face monitoring point of current time and beach;
Step 33, with the horizontal range on initial time dried beach face monitoring point and beach top, ask difference operation to carry out modulo operation more earlier with the horizontal range on this dried beach face monitoring point of current time and top, beach, obtain this dried beach face monitoring point far from the current measuring error of top, beach horizontal range; All handle according to this step for each dried beach face monitoring point, obtain each dried beach face monitoring point far from the current measuring error of top, beach horizontal range.
Need to prove in this step, because in one period long period, the variation of doing the surface, beach is similar to can regard a constant height lifting process of dried beach surface global shape as, therefore in this time period, dried beach surface curve equation that initial time should be done monitoring section place, beach still can truly reflect the fluctuating situation on the surface, dried beach at this dried beach monitoring section place, this dried beach surface curve equation can be directly as the dried beach surface curve equation of current time; Determine the error of initial time dried beach surface curve equation whether error tolerance band in initial time and each dried beach face monitoring point of current time with the horizontal range on top, beach by contrast, show then in the error tolerance band that initial time is somebody's turn to do the fluctuating situation that the dried beach surface curve equation of doing monitoring section place, beach can't truly reflect the surface, dried beach at this dried beach monitoring section place if surpass, need simulate the dried beach surface curve equation of current time again, otherwise show that then initial time should do the fluctuating situation that the dried beach surface curve equation at monitoring section place, beach still can truly reflect the surface, dried beach at this dried beach monitoring section place, can be directly with the dried beach surface curve equation of the initial time dried beach surface curve equation as current time;
Step 4, according to the current measuring error of each dried beach face monitoring point far from top, beach horizontal range, and predetermined measuring error critical value is determined the dried beach surface curve equation that current time should be done monitoring section place, beach.
Particularly, (this measuring error critical value can be by mine tailing storehouse scale with predetermined measuring error critical value far from the current measuring error of top, beach horizontal range with each dried beach face monitoring point, the length on Gan Tan inclined-plane, factors such as the precision prescribed of measurement result are determined, for example: this measuring error critical value can be 40.0, when thinking that doing the beach profile morphology does not change less than 40.0 the time, namely doing beach beach face curvilinear equation does not need to change) compare, if have two or more dried beach face monitoring points far from the current measuring error of top, beach horizontal range greater than scheduled measurement error critical value, then simulate current time again and should do the dried beach surface curve equation at monitoring section place, beach, should do the dried beach surface curve equation that the section place is monitored on the beach otherwise directly initial time is somebody's turn to do the dried beach surface curve equation of doing monitoring section place, beach as current time.
Further, again simulate this dried beach surface curve equation of doing monitoring section place, beach of current time and can comprise following process: the absolute altitude that obtains each auxiliary sighting point of current time, and according to the absolute altitude of each auxiliary sighting point of current time, and the absolute altitude of each monitoring point of current time that records in the step 3 simulates the dried beach surface curve equation that current time should be done monitoring section place, beach again.Similar with the absolute altitude that obtains each auxiliary sighting point of initial time, the absolute altitude of each auxiliary sighting point of current time also can adopt total powerstation to record; Again it is identical with the method for the dried beach of match initial time surface curve equation to simulate the method for doing beach surface curve equation according to the absolute altitude of the absolute altitude of each auxiliary sighting point of current time and each monitoring point, so repeat no more herein.
Step 5, according to current time water level absolute altitude, and the dried beach surface curve equation that current time should be done monitoring section place, beach determines the dried beach length that current time should be done monitoring section place, beach, thereby realized the measurement to length of dry sand of tailings reservoir.
Particularly, since do the surface, beach the real-time curve The Representation Equation be do under the real time status absolute altitude of certain point on the surface, beach and this point to the beach apex distance from funtcional relationship, therefore as long as current time water level absolute altitude is updated to the dried beach surface curve equation that current time should be done monitoring section place, beach, just can draw the horizontal range that push up to the beach current time flowage line monitoring point, just current time is done beach length, thereby has realized the measurement to length of dry sand of tailings reservoir.
Except technique scheme, the measuring method of the length of dry sand of tailings reservoir that the embodiment of the invention provides can also comprise: the approximate absolute altitude that can be regarded as the top, beach of the absolute altitude of top, beach auxiliary sighting point, the absolute altitude of top, the beach auxiliary sighting point that records according to initial time, and the corresponding relation of the absolute altitude on top, default beach and design flood level can be determined the design flood level in this mine tailing storehouse of initial time, the absolute altitude of top, the beach auxiliary sighting point that again initial time is recorded, ask difference operation with the design flood level in this mine tailing storehouse of initial time, just can obtain the safe superelevation in dried beach in this mine tailing storehouse of initial time.
Wherein, the safe superelevation in dried beach refers to the absolute altitude on top, beach and the design flood level in mine tailing storehouse, and (each mine tailing storehouse is before formally coming into operation, all will determine the borderline risk water level that may cause security incident in this mine tailing storehouse according to the geographic position in this mine tailing storehouse, the factors such as shape in this mine tailing storehouse, this water level is commonly referred to design flood level; The design flood level in mine tailing storehouse is not a fixed value, but the one group of numerical value that constantly changes along with the increase of top, beach absolute altitude; The mine tailing storehouse can pre-establish the absolute altitude on beach top and the corresponding relation between the design flood level before formally coming into operation, as long as therefore record the design flood level that the absolute altitude on top, beach just can be determined the mine tailing storehouse) the discrepancy in elevation; It also is one and weighs the whether important indicator of safe operation of mine tailing storehouse, also may cause water level in the storehouse in and overflow security incidents such as top, the dam break of mine tailing storehouse if exceed standard, so ten minutes is necessary the safe superelevation in dried beach in mine tailing storehouse is monitored.
Particularly, because in one period long period, the absolute altitude on top, beach almost is not change, therefore when the dried beach of initial time surface curve equation can reflect truly that the fluctuating situation on surface, beach is done at this dried beach monitoring section place, the absolute altitude on the top, beach of current time still equals the absolute altitude on top, initial time beach, and the safe superelevation in dried beach of current time still equals the safe superelevation in dried beach in this mine tailing storehouse of initial time.When the dried beach in initial moment surface curve equation can't reflect truly that the fluctuating situation on surface, beach is done at this dried beach monitoring section place, do beach surface curve equation and need match again, need record the absolute altitude of top, beach auxiliary sighting point again, therefore just can determine the safe superelevation in dried beach of current time according to the absolute altitude of top, the beach auxiliary sighting point that records again.
Need to prove, because the measuring method that the embodiment of the invention provides is being provided with the monitoring point with flowage line apart from the water surface less than 5 meters, the absolute altitude of reservoir level can obtain by this monitoring point, and in the reservoir level of the prior art monitoring at the aboveground measurement mechanism that the reservoir level absolute altitude also is installed of the flood discharge of mine tailing Kuku tail, therefore the absolute altitude of the reservoir level that records of two places can relatively be revised mutually, and then can solve in length of dry sand of tailings reservoir monitoring and reservoir level monitoring owing to observation station is different, the measurement elevation that precision is not enough and cause is closed-ended question not.
As fully visible, the embodiment of the invention can be measured in real time, accurately, reliably and do beach length, thereby truly accurately reflects the actual safety case in mine tailing storehouse, effectively reduces the risk that mine tailing storehouse security incident takes place.
