Description
(1) technical field
The invention belongs to the mine surveying setting-out technique, the longitudinal calibration method during particularly a kind of vertical shaft equipment is installed.
(2) background technology
Mineral exploration engineering is extended to middle deep in recent years, the main developing mode of deep orebody during shaft development has become.The precision that vertical shaft equipment is installed directly has influence on the lifting operational effect, yet vertical shaft equipment field engineering is complicated, and difficulty of construction is bigger; The pit shaft erecting equipment is many, and the relative position precision prescribed is high, and the careless slightly vertical shaft cage that will cause moves unbalance stress; Wearing and tearing are big, even security incident occurs.Therefore in the vertical shaft installation process, accurately the design attitude of calibration facility is most important.Traditional vertical shaft equipment installation site scaling method is directed for the suspension vertical line; Between interbedded distance and layer; The suspension steel ruler is measured mine shaft depth; Utilize surveyor's staff marking X1-Xn (being generally more than 10 points) on the borehole wall, and with this as a surface level, and utilize Y and the relation between the Z coordinate of vertical line to confirm the lateral attitude (referring to accompanying drawing 3) that pit shaft is installed.The said method measuring process is complicated; And there are many artificial factor; Like sight line influence, ruler out of plumb etc.; Temperature, the chi of chaining error (at present homemade long steel ruler equipment is less) and steel ruler are long because short steel ruler is connected again, correction is extended in deadweight, and the pit shaft air-flow and the influence of dripping, and cause measuring error bigger.And along with pit shaft is installed decurrence, error accumulation, the influence of the precision that equipment is installed further enlarges; Moreover mostly surveying work be to operate in the pit shaft, and difficulty is bigger.
(3) summary of the invention
The object of the present invention is to provide the longitudinal calibration method of a kind of new vertical shaft equipment in installing, overcome the shortcoming that existing procedure is complicated, alignment error is big, operation easier is big.
The technical scheme that the present invention adopts is following:
Longitudinal calibration method during a kind of vertical shaft equipment is installed comprises the layout of measuring vertical line, the setting-out of confirming and the surface level device location being installed of horizontal mounting surface, wherein:
1) measure being arranged as of vertical line: at first confirm vertical line position: along two main beams design 3-4 bar vertical line, vertical line is between two main beams, and the horizontal range between the crossbeam that closes on is 1-3cm; Setting-out goes out the planimetric position of vertical line and pit gear and the initial absolute altitude of installation and design of vertical line point place pit shaft on the well face shaft cover of interim sealing then, and makes precise marking; Cut a hole the unwrapping wire hole at shaft cover vertical line position place, put vertical line, described vertical line adopts identical material, and the lower end hangs with weight;
2) confirming of horizontal mounting surface: confirm the installation and control plane through putting into the identical 3-4 bar vertical line of length, the length of putting into vertical line through control is confirmed the degree of depth on plane.
Though three vertical line points can be confirmed a mounting plane, in order to be convenient to install the setting-out of surface level device location more, preferably the bar number of the vertical line of edge two main beams design is 4, respectively has two to close on same main beam.
Further, the setting-out of said installation surface level device location is: the distance parameter that adopts geometirc graphical calculation to calculate two groups of parallel edges of pit gear position and control plane (surface level promptly is installed) gets final product.Certainly, it also is feasible adopting other setting out method.Wherein, according to the mark parameter in the facility installation drawing, directly setting-out goes out the device location of this installation surface level with fine rule rope, wire clips (mark is used), Steel Ruler.
Described geometirc graphical calculation is meant the distance that calculates equipment installation site and the tetragonal limit of being made up of four vertical line points that surface level is installed according to method of geometry.For example; Confirm the position of a facility point on the borehole wall; In geometric figure, be this point and did and installed the parallel lines on a limit (four straight lines that vertical line point is formed) in the surface level; The parallel lines of making should have intersection point with limit or its extended line of controlling level face, and we only need measure the distance of intersection point to vertical line point, on design drawing, have made mark just.Two parallel lines that only need draw four vertical line points during downhole operations are measured the distance of design as baseboard, and wire clips makes a mark, and the intersection point that draws the straight line and the borehole wall is the position of the facility of asking.
Further again, described vertical line adopts the high carbon spring steel wires of tensile strength to process, the carbon spring steel wires of preferred Φ 1-1.5mm.
Say that simply the present invention is a characteristic of utilizing vertical line, hand on the well head surface level is parallel successively,, vertical shaft equipment is accurately demarcated through geometirc graphical calculation as the control plane that vertical shaft equipment is installed.
In the arrangement stage of measuring vertical line,, therefore adopt along two main beams design vertical line because the installation accuracy of pit guide crossbeam and vertical beam is the key factor of cage and balance bob running quality.Need take into full account the stated accuracy of major equipment or facility and the strength of figure of controlling level face (parallelogram is not as rectangle, and the longer the better for the length of side) and suspension vertical line, pit gear timing signal operation facility on the vertical line arrangement principle.
Concrete, be advisable with ￠ 5mm at shaft cover vertical line position cutter unwrapping wire hole size, through leading block and winch fixed vertical line are installed, repeated measurement, check errorless after, put vertical line again.For preventing that vertical line from contacting with pit gear, need put collar inspection behind each unwrapping wire; Simultaneously can on lower floor's tool stand, place stabilizing solution,, guarantee that vertical line is vertical to overcome the weight swing.Selecting for use of vertical line is thin, corrosion-resistant with diameter, the high strength material is excellent, and carbon spring steel wires promptly is good selection.Carbon spring steel wires is made a mark for every meter in well face standard tension (parameter of dispatching from the factory hangs 10 kilograms of weights approximately) effect down.
According to utilizing two vertical lines the coordinate of well face two known points to be transmitted the principle (directed, lead height) of down-hole through connection triangle method in the vertical shaft one well orientation survey; According to Hooke's law; Under the identical condition, the weight of four weight such as vertical line suspension, amount of tension is identical.To carbon spring steel wires, its different length the weight that should select for use and the corresponding stretcher strain amount reference table 1 of corresponding weight.When four vertical lines are put the same degree of depth; 0 meter gauge point can be confirmed a horizontal mounting surface; Amount of tension Δ L (parameter of dispatching from the factory adds that external condition influences correction) and wire rope by steel wire mark length in advance, can calculate 4 points on the installation surface level of trying to achieve demand absolute altitude in the pit shaft.Utilize steel wire characteristic (vertical line of other identical materials also possesses this characteristic); Overcome the influence of the instrumental error in the classic method, observational error and external condition; Improved the location position precision of equipment; And successively the known installation and control surface level of well head is handed on, and saved downhole operations, increased operability.The pit gear position adopts geometirc graphical calculation to obtain by the level control cross section of vertical transmission in addition, has optimized the demarcation scheme, has improved precision.Simplified measuring process simultaneously, especially wellbore operations time few, reduced labour intensity, saved the set-up time, increased the feasibility of operation.
Weight was selected and every meter amount of tension of steel wire (reference value) during table 1 vertical shaft equipment was installed
| Mine shaft depth (rice) | Weight weight (kilogram) | Every meter amount of tension (millimeter/rice) | Remarks |
| ＜300 | 75 | 1.17 | |
| 300-400 | 100 | 1.56 | |
| 400-500 | 125 | 1.95 | |
| 500-600 | 150 | 2.34 | |
| ＞600 | 175 | 2.73 |
Annotate: data from the steel wire parameter of dispatching from the factory, the steel wire amount of tension of unlike material, different-diameter is different, can be well face practical measurement (external condition influences I and ignores) in the table.
Further, the present invention adopts carbon spring steel wires as vertical line, also has following advantage:
1, volume receives the pit shaft air-flow and the influence of dripping can be ignored for a short time; 2, the same terms stretched amount is stable; 3, the deadweight elongation is corrected and can be ignored; 4, steel wire expansion coefficient a=0.0000115 rice/degree also can be ignored in pit shaft is installed (like 600 meters in pit shaft, 5 ℃ of the well face and the pit shaft temperature difference are then tried to achieve Δ L according to formula Δ L=a.L Δ t and be merely 0.0345 meter).
In pit shaft was installed, classic method was demarcated one deck bunton 90 minutes, adopted this method only to need 40 minutes, had simplified measuring method greatly and had shortened Measuring Time; Install in addition that height error is ± 2 millimeters between the bunton, reach non-coal mine installation engineering quality check evaluation criterion ± 5 millimeters (within error range).
