Practice shows that the reinforced wall is simple in structure, high in mechanical construction, low in construction cost and capable of effectively controlling peripheral diffusion of the bottom of the waste dump caused by settlement, guaranteeing mine safety production and obtaining good economic benefits and social benefits, and the reinforced wall is made of local materials.
Description
Technical field
The present invention relates to Mine production technical fields, and in particular to a kind of desert and Gobi Mine production ground anti-settling
The production method of reinforcement walls.
Background technique
As under the strategic decision of national development of the West Regions, there is a large amount of mine in especially western Desert of Gobi area exploitation
And refuse dump.And it is loosening sand layer that western Desert of Gobi area surface layer, which is mainly the 4th, the layer is thicker big, to mine casting
Field construction is very unfavorable, especially causes production safety problem because ground substantially settles to large and medium-sized refuse dump.Area, China at present
Waste dump processing in domain fills out the methods of base, dynamic-ramming gravel pile using whole soil removal and replacement substantially, though and these methods solve sedimentation
The problems such as, but since these methods are at high cost and construction method is complicated, popularization and application are restricted, and the prior art can not solve
State problem.
Summary of the invention
The purpose of the present invention is to solve Waste dump processing cost in the prior art, high and construction method is complicated,
Very restricted problem is promoted and applied, a kind of production side of desert and Gobi Mine production ground anti-settling reinforcement walls is provided
Method.
In order to achieve the above object, the invention adopts the following technical scheme: a kind of desert and Gobi Mine production ground is anti-
The production method for settling reinforcement walls, comprising the following steps:
1) ground divides arrangement: being first that soft Waste dump divides to the 4th, forms the side of sphere of movements for the elephants trellis
Grid；
2) it excavates: being soft Waste dump as benchmark to divide the finish the 4th, be excavated to along grid
Supporting course, formed after excavation excavate it is suitable for reading, excavate bottom, the excavation slope angle α formed after excavation be equal to loosening sand layer from
Right angle of repose；
3) fill: mine truck transports high-strength barren rock and carries out slicing and filling discharge to part is excavated later, then uses again
The smooth processing of frontloader；
4) it heap dam: is handled again using high-strength hillock row based on the ground after excavating part and filling by, heap row
The heap dam that section is " trapezoid " shape is formed afterwards, and the bottom on heap dam is to excavate heap dam side slope suitable for reading, both sides are formed after heap row
Angle beta is equal to the natural repose angle of high-strength barren rock；
5) it forms: ultimately forming the reinforcement walls that a section is hexagon, reinforcement walls section is that the part of " inverted trapezoidal " exists
Close to supporting course below earth's surface, reinforcement walls section is the part of " trapezoid " more than earth's surface.
As a further improvement of that present invention, what the small grid that the grid in step 1) is 100m × 100m was formed
Sphere of movements for the elephants trellis grid.
As a further improvement of that present invention, in step 2 excavate bottom width be 6~8m, excavate width suitable for reading be 18~
24m, cutting depth are 6~8m.
As a further improvement of that present invention, excavation slope angle α is 37 °~45 ° in step 2.
As a further improvement of that present invention, the high-strength barren rock in step 3) is dew of the Polodyakonov coefficient coefficient between 8~20
Fresh protolith after its stope explosion.
As a further improvement of that present invention, the top width on step 4) heap dam is 6~8m, and the height on heap dam is 6~8m.
As a further improvement of that present invention, step 4) heap dam slope angle β is 39 °~45 °.
The present invention compared with the existing technology, has the advantages that desert and Gobi Mine production ground of the invention
The production method of anti-settling reinforcement walls is excavated, is filled by the production benchmark with sphere of movements for the elephants trellis grid formation reinforcement walls
Fill out, heap dam, the processes such as molding handle Waste dump using reinforcement walls, ultimately form the reinforcing that a section is hexagon
Wall, the intensity and actual condition that are undertaken according to wall determine the size of wall, and casting height is made to reach 60m, with original row
Tu Chang is compared, and sedimentation is greatly reduced, and is limited refuse dump sedimentation bring horizontal stress, is effectively controlled refuse dump bottom
Circumference diffusion.The configuration of the present invention is simple, high mechanization construction, reinforcement walls are gathered materials on the spot, and construction cost is cheap, effectively controls
Because the diffusion of refuse dump bottom perimeter is carried out in subsiding belt, is provided safeguard for Mine Safety in Production, achieve good economic benefits and society
Benefit.

Specific embodiment
Present invention will be further explained below with reference to the attached drawings and specific embodiments.
As shown in Figs. 1-2, a kind of production method of desert and Gobi Mine production ground anti-settling reinforcement walls, including it is following
Step.
1) ground divides arrangement: being first that soft Waste dump 1 divides to the 4th, forms 100m × 100m's
The grid 2 of the sphere of movements for the elephants trellis of small grid composition.
2) it excavates: being soft Waste dump 1 as benchmark to divide the finish the 4th, excavated along grid 2
Formed to supporting course 3, after excavation excavate it is suitable for reading 5, excavate bottom 4, section is " inverted trapezoidal " shape after excavation, and it is general to excavate suitable for reading 5
For 18~24m, cutting depth is determined that general cutting depth is 6~8m by the thickness of sandy soils, and the width for excavating bottom 4 depends on
The width of mine truck is travelled in the intensity and digging process that wall is undertaken, generally 6~8m, both sides are formed after excavation
Excavation slope angle α is equal to the natural repose angle of loosening sand layer, and excavation slope angle α is 37 °~45 °.
3) fill: mine truck transports 6 pairs of excavation parts of high-strength barren rock and carries out slicing and filling discharge, high-strength barren rock 6 later
Fresh protolith after the excavating plant explosion for being Polodyakonov coefficient coefficient between 8~20.Then the smooth processing of frontloader is used again,
Convenient for driving, mine truck carries out rolling pressure during transporting high-strength barren rock 6 to the high-strength barren rock 6 of filling and discharging
It is real, certain intensity is formed, until all filling is completed to part is excavated.
4) heap dam: to carry out high-strength 6 heap row of barren rock processing, heap row again based on the ground after excavating part and filling
The heap dam 7 that section is " trapezoid " shape is formed afterwards, and the width on heap dam 7 depends on the top of intensity and heap dam 7 that heap dam 7 is undertaken
The width of the mine truck travelled in portion, the top width on heap dam 7 are generally 6~8m, and heap dam bottom is to excavate suitable for reading 5, heap
The height on dam 7 depends on the intensity that heap dam 7 undertakes for a long time, and the height on heap dam 7 is generally 6~8m.Both sides are formed after heap row
Heap dam slope angle β is equal to the natural repose angle of high-strength barren rock, and heap dam slope angle β is 39 °~45 °.
5) it forms: ultimately forming the reinforcement walls that a section is hexagon, reinforcement walls section is that the part of " inverted trapezoidal " exists
Close to supporting course 3 below earth's surface, reinforcement walls section is the part of " trapezoid " more than earth's surface.
