Abstract
The present method is used for mining inclined thin ore body, which is characterized by that it organically combines the column charge hole wall effect 90 deg. rupturing principle and mining process, and its heel utilization rate is high, and its blasting energy utilziation rate is high, said method can be used in the ore body whose thickness is 3 m, it has no need of digging bottom structure, and has no need of cutting groove, only has need of using mine outlet driftway as free surface to make slashing and extraction, so that it can greatly reduce mining engineering quantity.
Description
The invention belongs to the underground mining method of the various valuable minerals of field of mining, in particular for the exploitation of inclination narrow orebody.
In the inclination narrow orebody, use the exploitation of traditional mining methods, why mainly there are two defectives in the cost of production height, and the first, adopt that to cut engineering quantity big; The second, the blasting energy utilization rate is low.
The purpose of this invention is to provide a kind of energy-saving demolition mining method adopting columnar cartridge, can overcome the weak point of traditional mining methods,, reduce mining cost significantly to improve mining efficiency.
The technical scheme that the present invention achieves the above object is that break principle and mining technology of 90 ° of column cartridge bag hole wall effects organically made up, it is characterized in that: the inclination narrow orebody is divided into the panel back production, at first at haulage level excavation haulage way 1, then driving up rock drilling with the mineral building width goes up a hill 2, then to driving ore removal tunnel, one or both sides 3, back production big gun hole 6 Drillings are on ore removal tunnel 3; Go up a hill in 2 in rock drilling then, over against the another side excavation scraper hoist chamber 5 in ore removal tunnel 3; Along with substoping stays goaf 7, on one side ventilation connecting taxiway 4 excavates by the dead zone in the superiors on the panel; The 3 Drilling back production big gun holes 6 in the ore removal tunnel, and load onto the column cartridge bag; Utilize the quick-fried energy of column cartridge bag, with ore from the stope throwing in the ore removal gallery; One section not powder charge is stayed along rock drilling courtyard 2 in column big gun hole, stay residual hole 8 after the explosion, just formed a protection ore pillar; Collapse down ore and take off to rock drilling from cutter tunnel, ore deposit 6 one ends by scraper and go up a hill 2, be total ore removal to go up a hill, take off to haulage drift 1 dress ore deposit by scraper again and transport.
Compared with the prior art the present invention, has shown following advantage in the practical application of underground mining:
1. blast hole utilizing factor height, the back production big gun hole of Drilling in narrow orebody, the rock drilling that both can form the front is gone up a hill, residual big gun hole all can be utilized again and carry out back production, stay the residual hole in the ore pillar, also can not destroyed, in the panel back production later stage, utilize again and reclaim the ore pillar ore.
2. blasting energy utilization rate height, during column charge blasting, gas pressure the energy-producing overwhelming majority rush at perpendicular to big gun hole 6 axis laterally, consistent with the ore removal direction, but both back production ore caving of blasting energy can be transported to assigned address with ore again.
3. energy-saving demolition mining method adopting columnar cartridge is used in the thick ore body of 3m, has not both dug polycrystalline substance, does not also draw cutting groove, as long as utilize the ore removal gallery to carry out back production for scope of freedom explosion, has reduced significantly to adopt and has cut engineering quantity, remarkable in economical benefits.
When 4. the energy-conservation blasting technique of column cartridge bag was used digging laneway, every index obviously is better than conventional method, and was as shown in table 1.
The comparison of energy-conservation blasting technique of table 1 column cartridge bag and traditional handicraft
| Index | New technology | Traditional handicraft | Index | New technology | Traditional handicraft |
| Blasthole diameter (mm) | ????58 | ??38-42 | Digging footage (m) | ????2～2.4 | ????1.3 |

Be further described below in conjunction with accompanying drawing:
Fig. 1 is the sectional drawing of energy-saving demolition mining method adopting columnar cartridge across pitch.
Fig. 2 is the sectional drawing of energy-saving demolition mining method adopting columnar cartridge capwise.
Numbering implication in the accompanying drawing:
Haulage way 1; Courtyard 2; Ore removal tunnel 3; Ventilation connecting taxiway 4; Scraper hoist chamber 5; Deep hole 6; Goaf 7; Residual big gun hole 8 in the ore pillar.
Accompanying drawing 1 is exactly the example of an enforcement, has described the job step of the energy-conservation mining methods of column.
The inclination narrow orebody is divided into the panel back production, at first at haulage level excavation haulage way 1, in haulage way 1, drive up rock drilling and go up a hill 2, go up a hill in 2 to one or both sides driving ore removal gallery 3, in the rock drilling 3 Drilling back production big gun holes 6, parallel ore removal tunnel in 2 of going up a hill in rock drilling with the mineral building width; Along with the back production of segmentation stays goaf 7, on one side excavate ventilation connecting taxiway 4 by the dead zone in the superiors in panel; Go up a hill in 2 in rock drilling, over against the another side excavation scraper hoist chamber 5 in ore removal tunnel 3; Utilize the blasting energy of column cartridge bag, with ore from the stope throwing in the ore removal gallery; For safety, one section not powder charge is stayed along rock drilling courtyard 2 in column big gun hole, stay residual hole 8 after the explosion, just formed a protection ore pillar; Collapse down ore and taken off to rock drilling from cutter tunnel, ore deposit 6 one ends by scraper and go up a hill 2, go up a hill for total ore removal this moment, taken off by scraper and adorn the ore deposit to haulage drift 1 and transport.
