Abstract
A collaborative mining method for a common ore storage section with multi-branch draw shafts in stopes arranged in stepped manner comprises following steps: a level haulage roadway along a vein is excavated in a footwall surrounding rock of an ore body, an ore outlet funnel is arranged on one side of the haulage roadway, raise-boring is performed above a funnel opening, the ore storage section is formed, and a plurality of draw shafts are excavated in a fan shape at the top end of the ore storage section so as to communicate stope drifts of layered mine stopes; rib pillars are reserved on intersection lines of the draw shaft planes and the ore body plane; the layered mine stopes are arranged in the stepped manner, and mine stope backstopping operation is performed with a room-and-pillar method; caved ore of the mine stopes is transferred to the common ore storage section by an electric rake and transported to the earth surface by an electric locomotive. The method has the advantages that mutual interference of backstopping of ore beds is small, the ore productivity is high, the mine stope production capacity is high, and the like.
Description
Technical field
The present invention relates to a kind of mining methods of metal mine underground mining, specifically a kind of stope step arranges that multiple-limb drop shaft is store ore deposit section altogether and worked in coordination with mining codes, is applicable to point to adopt the firm multiple-layer horizontal of country rock or gentle dip is as thin as middle thickness orebody.
Background technology
Room and pillar stoping is mainly used in the exploitation firm level of country rock or gentle dip is as thin as middle thickness orebody, in nugget or exploiting field, mineral building and ore pillar are alternately arranged, the regular ore pillar of continuous print or interruption is stayed during rooming, to safeguard balkstone, it has adopts that to cut engineering quantity little, and job engineering is simple, and mine timber consumption is few, well-ventilated, mineral building production capacity high.
Multiple-layer horizontal or gentle dip are as thin as the traditional exploitation method of middle thickness orebody and mainly contain conjunction and adopt or point adopt two kinds of modes.Often select when interlayer is thinner conjunction to adopt, select when interlayer is thicker to divide and adopt.Point adopting in mode, by the restriction of ore removal structure and ore removal equipment, generally first exploiting upper strata ore body, successively back production lower floor ore body again after having adopted, the stoping operation interference of each ore bed is large, does not have independence, carrying process limits by stoping operation, makes production capacity of mining field low, and job engineering is complicated.
Summary of the invention
The object of the invention is to solve the technical barrier that multiple-layer horizontal or gentle dip are as thin as middle thickness orebody slicing, multiple-limb drop shaft is store ore deposit section altogether and is worked in coordination with mining methods to provide a kind of stope step to arrange, it can overcome multilayer ore body and divide when adopting, the exploitation adopting conventional drop shaft to bring is inharmonious, the shortcomings such as mining authority is complicated, improve each ore bed storage ore deposit section capacity, harmony etc. between ore drawing in stope and funnel ore drawing, reduce interacting and conditioning each other in multilayer ore body exploitation process to greatest extent, realize efficiently intensive in production space, finally realize the safety of multilayer ore body, efficiently, the collaborative exploitation of low cost.
For solving above-mentioned technical barrier, the technical solution used in the present invention is: a kind of stope step arranges that multiple-limb drop shaft is store ore deposit section altogether and worked in coordination with mining methods, comprises the steps:
1 each layering ore body across pitch multiple-layer horizontal or gentle dip country rock being firmly as thin as middle thickness orebody is divided into stope, and each layering ore body stope step is arranged, carry out stope mining operation by room-and-pillar method, multiple-limb drop shaft works in coordination with ore removal;
2 tunnel a level haulageway along the pulse in ore body lower wall country rock, and an ore removal funnel is arranged in level haulageway side along the pulse, for the synchronous ore removal of multilayer ore body, again by large for brush above ore removal bell mouth, form common storage ore deposit section, being the some drop shafts of fan cut on storage section top, ore deposit to undercut tunnel to be communicated with each layering stope;
3 according to mine actual conditions, and arrange each key element of stope, stope broken ore is stored to common storage ore deposit section through tunnel-drop shaft of going up a hill-undercut, and is finally transported to earth's surface by electric locomotive.
Described ore removal funnel is 1.2m × 1.5m.
Described drop shaft is 1.5m × 1.5m.
The described tunnel that undercuts is 2m × 2m.
Described staying on the intersection of drop shaft plane and ore body plane sets studding as 5 ~ 8m.
Outstanding technical characterstic of the present invention is:
1, can make the restriction of multilayer ore body not by other ore bed back production in back production, each ore bed stoping operation disturbs little mutually, embodies each layer ore body and divides the concertedness of adopting.
2, multiple-limb drop shaft is store ore deposit segment structure altogether and is considerably increased storage ore deposit ability, efficiently solves the problem of Ore Transportation by drop shaft storage ore deposit ability restriction, reduces Ore-mining Management difficulty and the labor productivity that improve workman simultaneously.
Accompanying drawing explanation
Fig. 1 is that stope step of the present invention arranges that multiple-limb drop shaft stores the schematic three dimensional views that ore deposit section works in coordination with mining methods altogether.
Be labeled as in figure: 1-level haulageway 2-funnel 3-stores ore deposit section 4-drop shaft 5-and to undercut tunnel 6-studding.
Detailed description of the invention:
As shown in Figure 1, stope step of the present invention arranges that multiple-limb drop shaft is store ore deposit section altogether and worked in coordination with mining methods, comprise the steps: to tunnel a level haulageway 1 along the pulse in ore body lower wall country rock, 1.2m × 1.5m ore removal funnel 2 is arranged in haulage drift 1 side, storage ore deposit section 3 is formed by large for 2 mouthfuls, funnel top brush, storage section 3 top, ore deposit be the some 1.5m × 1.5m drop shafts 4 of fan cut, drop shaft driving, inclination angle minimum by engineering quantity meets ore from slipping principle, to undercut tunnel 5 to be communicated with each layering stope 2m × 2m; The intersection of drop shaft plane and ore body plane stays and establishes 5 ~ 8m studding 6; Deposit situation according to the actual tax of ore body, each layering stope step is arranged, carries out stope mining operation by room-and-pillar method; Stope broken ore is transported to common storage ore deposit section by scraper, is transported to earth's surface by electric locomotive.
