Description
Technical field
The invention belongs to mining technique fields, and in particular to rock drilling layering falls mine shrinkage mining method in a kind of arteries and veins.
Background technology
With the continuous development of China's mineral industry, the preferable mine of mining conditions has been exploited totally, remaining exploitation is difficult,
Orebody occurrence is poor, and the exploitation in the mines such as ore complex shape is urgently to be resolved hurrily.Wherein, ore roof and floor country rock stability compared with
The mining difficulty of difference, the inclined lean ore body of ore body is larger, and ore recovery rate is low in recovery process, causes ore further
Loss, reduces the economic benefit of bargh, it is often more important that in exploitation process, often also needs to cooperation man-made recovery, labor
Fatigue resistance is big, in fact it could happen that such as top plate avalanche, ore pillar destroy and a series of disasters of surface subsidence, causes to damage to personnel and equipment
Evil greatly threatens the safety in production in mine.
In addition, explosion can cause periphery barren rock to be mixed into ore, and when using ore drawing under overlying strata, it can also make barren rock
It is mixed into advance, ore dilution rate is caused to rise, if using cut off grade ore drawing, it will cause a large amount of ore losses.Tradition
Shrinkage method be faced with the difficulty of ore losses, production safety etc., need to improve.
Invention content
Present invention aims at provide a kind of solution safety problem in the poor lean ore body recovery process of ore stability
And underground pressure management problem, raising ore recovery rate, the mining methods for reducing depletion loss.
In order to achieve the above objectives, as follows using technical solution：
Rock drilling layering falls mine shrinkage mining method in a kind of arteries and veins, includes the following steps：
By the ore body division stage, across pitch arranges continuous nugget in the stage；The tunnel that undercuts along the pulse is tunneled along ore body lower wall,
The side driving drawing chute of stage transportation roadway reaches ore body, using haulage drift on last stage as this rank when each stage back production
The tailgate of section；
In ore body lower wall driving people's row vent (-escape) raise and next stage haulage level in ore chute unicom, in people's row ventilation day
Well leads to stope with driving layering connection roadway in ore chute；
Nugget from top to bottom slicing, by layering connection roadway along orebody trend driving slicing tunnel；Slicing
After tunnelling, the top in shallow blasting or free breakage slicing tunnel, side ore；
Driving layering connection roadway and the ore in slicing tunnel are transported to the mine that ore chute unloads mine, explosion and avalanche
All layerings such as stone once fall mine after having adopted, and are transported to stage transportation roadway through drawing chute.
Compared with the existing technology, advantageous effect of the present invention is：
Compared with traditional shrinkage method, layer height is big, and primary excavation mine amount is big, and mining efficiency is high；
It is safe without in exposed region operation；
Operation is simple, is easy to grasp；
Arrangement and process for stoping are flexible, are suitable for the mine of occurrence condition complexity, to ore-rock stability without being important to
It asks, it is adaptable, have a wide range of application.

Specific implementation mode
Following embodiment further illustrates technical scheme of the present invention, but not as limiting the scope of the invention.
With reference to shown in attached drawing 1-3, in arteries and veins of the present invention rock drilling layering fall mine shrinkage mining method：
First by the ore body division stage, across pitch arranges continuous nugget in the stage, using on last stage when each stage back production
Tailgate 2 of the haulage drift as this stage is as shown in Figure 1 one of nugget.
The tunnel that undercuts along the pulse is tunneled along ore body lower wall, driving drawing chute 7 reaches ore body in the side of stage transportation roadway 6.
In ore body lower wall driving people's row vent (-escape) raise 3 and next stage haulage level in 5 unicom of ore chute, in vent (-escape) raise 3 and ore drawing
Driving layering connection roadway 1 leads to stope in drop shaft 5, and the layering connection roadway at stope both ends should be staggeredly arranged.
Nugget from top to bottom slicing, people's row vent (-escape) raise 3 or from the pick point of 5 vertical ore body of intermediate drop shaft at nugget both ends
Layer connection roadway 1, after along orebody trend driving slicing tunnel 4.
Actual mining is mainly after slicing tunnel 4 has been dug, with shallow blasting or free breakage back production top, side mine
Stone, be layered the ore that connection roadway 1 and slicing tunnel 4 are tunneled be transported to-ore chute 5 unloads mine, the ore 8 of explosion avalanche etc.
All layerings once fall mine after having adopted, and are transported to stage transportation roadway 1 by mine truck through funnel 7, then be transported to earth's surface along blind inclined shaft
Stockyard.
