Abstract
The invention discloses a filling mining method after large diameter long-hole ore caving. The filling mining method comprises the following steps that firstly, as for a large cavern zone, a blasting sequence and a mining sequence are changed, and the cavern zone serves as compensation space for blasting; secondly, a long-distance blasting mode is used, namely, the mode that adjacent stope roadways are subjected to long-distance punching, powder charging, blasting and the like is used, so that the problem of ore falling of an ore body, on which excavating or rock drilling and powder charging cannot be conducted, in the cavern zone is solved; and thirdly, as for a small-scale cavern zone, relative materials are used for strengthening and repairing blastholes. A filling process which takes tailings, dead rock and the like as filling materials, is conducted in dependence on two pumping modes of automatic flowing and pumping, is based on tailing cement filling and combines dead rock cement filing and dead rock filling is formed. Ground pressure is effectively controlled; operation safety is guaranteed; the mining cost is reduced; and destruction of the dead rock to a mine environment is reduced by a large margin.
Description
Technical field
The present invention relates to a kind of mining methods, and in particular to a kind of large diameter, deep borehole ore caving afterwards fills town mining methods, belongs to mining technique field.
Background technology
Gold deposit belt preservation layer position is the silication tectonic breccia band at the Lower Proterozoic Pearl Gate group griotte plane of unconformity position that the red sinople sandstone in Qingbaikouan System of upper Proterozoic erathem fishing platform group bottom underlies with it, 4 industry ore bodies have been drawn a circle to approve altogether, wherein I ore bodies are mother-lode, II, III, IV ore bodies are secondary ore body, III ore bodies are low-grade ore body, the direct country rock of ore body is silication tectonic breccia, upper armor rock is fishing platform group quartzy sandstone, strata structure is complete, for the solid rock of thick-layer shape, ore body lower wall rock is Pearl Gate group griotte, for half hard one hard thick bedded rock, surrounding rock mostly is tectonic breccia, there is a certain degree of silication cementing in mineralizing process, some locations may not very consolidate, the location particularly cut by late period northwestward faults, rock has the broken of later stage, less stable, solution cavity area development in ore body, single solution cavity volume is maximum to reach 6300m3；Ore-rock crack and solution cavity are contained within a large amount of ponding, and one time maximal water*.inrush quality once reached 1700m3；Mining area surface has substantial amounts of good farmland, nearby there is Some Villagers and building, and earth's surface is not allow for big plate mausoleum interest ore deposit of subsiding and is located at Jilin Province's Baishan within the border, and mining area physical features belongs to Lower and middle mountain areas, and landform is more complicated；Solution cavity area development in ore body, ore-rock crack and solution cavity include a large amount of ponding, and coal mining geological condition is severe；There are a large amount of good farmlands in earth's surface, do not allow avalanche, there is a large amount of buildings and local resident near mining area, blasting vibration be required strict.
The content of the invention
（One）The technical problem to be solved
To solve the above problems, the present invention proposes a kind of large diameter, deep borehole ore caving and afterwards fills town mining methods, using different filling process and slurry pipeline transport mode, define and filler is done with tailings, barren rock etc., by gravity flow, pumping two big pumping modes carry out based on tailing cemented filling, the filling process that barren rock consolidated fill and waste fill combine, presses, ensures job safety, reduce mining cost, drastically reduce the area destruction of the barren rock to mine environment with efficiently controlling.
（Two）Technical scheme
The large diameter, deep borehole ore caving of the present invention afterwards fills town mining methods, comprises the following steps：
The first step：For larger solution cavity area, by changing blasting sequence and stopping sequence, implement explosion as compensation space by the use of solution cavity area, without the need for slot raise of constructing；
Second step：Using the blasting method of Separated striking tool, i.e., punchinged at a distance the modes such as charge explosion using adjacent stope tunnel, solve the problems, such as that solution cavity area cannot tunnel or rock drilling, the ore body of powder charge fall ore deposit, or using modes such as the opposite driling explosions of upper and lower segmentation；
3rd step：For the less solution cavity area of scale, then reinforced using associated materials, repair blasthole, impact of the solution cavity area to mining is avoided to greatest extent, reduce ore losses.
（Three）Beneficial effect
Compared with prior art, the large diameter, deep borehole ore caving of the present invention afterwards fills town mining methods, using different filling process and slurry pipeline transport mode, define and filler is done with tailings, barren rock etc., by gravity flow, pumping two big pumping modes carry out based on tailing cemented filling, the filling process that barren rock consolidated fill and waste fill combine, presses, ensures job safety, reduce mining cost, drastically reduce the area destruction of the barren rock to mine environment with efficiently controlling.
Specific embodiment
A kind of large diameter, deep borehole ore caving afterwards fills town mining methods, comprises the following steps：
The first step：For larger solution cavity area, by changing blasting sequence and stopping sequence, implement explosion as compensation space by the use of solution cavity area, without the need for slot raise of constructing；
Second step：Using the blasting method of Separated striking tool, i.e., punchinged at a distance the modes such as charge explosion using adjacent stope tunnel, solve the problems, such as that solution cavity area cannot tunnel or rock drilling, the ore body of powder charge fall ore deposit, or using modes such as the opposite driling explosions of upper and lower segmentation；
3rd step：For the less solution cavity area of scale, then reinforced using associated materials, repair blasthole, impact of the solution cavity area to mining is avoided to greatest extent, reduce ore losses.
Embodiment described above is only that the preferred embodiment of the present invention is described, and not the spirit and scope of the present invention are defined.On the premise of without departing from design concept of the present invention; various modifications and improvement that this area ordinary person makes to technical scheme; protection scope of the present invention all should be dropped into, the technology contents that the present invention is claimed all have been recorded in detail in the claims.
