Description
Technical field
The invention belongs to mining engineering technical field, specifically, is related to a kind of stoping method of difficult mining blocks.
Background technology
Dajishan wolframite found and exploited in 1918, and 1958 start regular mechanical mining, so far existing last 100 yearses
Production history, it is the maximum Quartz-vein Type Wolframite in the current whole world.Corporate restructuring in 2004, which is reassembled as Jiangxi Dajishan Mine tungsten industry, to be had
Limit company, it is subordinate to Tungsten In Jiangxi Province industry Group Co., Ltd.The former t/ of design selecting ability 81.2 ten thousand in mine.Existing production scale is 75
Ten thousand t/, the t of year digging total amount 350,000, produce tungsten concentrate amount 3080t per year.Ore-rock is mainly that the shallow metasandstone of Cambrian system and slate are mutual
Layer, hardness factor 8-10.Ore body is mainly high-dipping, extra narrow vein, and main mining method is shallow hole shrinkage method and stage mineral building
Method.
Mine finds in production process, and part nugget is tomography, broken crisscross due to being influenceed by structure destruction, generally
Exist in piece, rock mass is in cataclastic texture, and mechanical strength is low, during back production bucklingization it is violent, roadway deformation is serious, a large amount of pieces of stope
Help roof fall, to stope mining and ore drawing work bring very big potential safety hazard, cause construction speed slowly and oil in place loss and
The rate of extraction declines, and safety and cost management to mine bring very big pressure.
In existing ore body, tomography is crisscross, crushes serious, construction, joint, cranny development, rock crusher pole along the pulse
It is unstable.Large area collapses in tunneling process for former development heading along the pulse, if using regular shallow shrinkage method back production, worker and sets
It is standby to need to enter exploiting field, very big potential safety hazard be present.
For problem above, spy proposes the application.
The content of the invention
In order to solve problem above existing for prior art, the invention provides a kind of difficult mining blocks stoping method, the party
Method is safe and reliable, simple and easy, advanced technology, back production efficiency high, and worker and equipment need not enter exploiting field, it is achieved thereby that difficult
The back production of mining blocks, has reclaimed mineral resources to greatest extent, improves back production efficiency.
To achieve these goals, the present invention adopts the following technical scheme that：
A kind of difficult mining blocks stoping method, described method comprise the following steps：

Further, minimum burden is 2.5m~3m, bottom hole pitch 2.8m~3m in step (3).
Further, the blasthole spacing of step (4) borehole blasting is not more than 400mm, and blasthole is parallel to each other, and blasthole bottom hole is same
In one plane.
The present invention uses photoface exploision, carries out tunneling construction using smooth Surface Blasting Technology, reduces the destruction to peripheral rock.
Further, step (4) borehole blasting uses plastic detonating tube-non-electrical millisecond delay cap initiation system and primacord
Dual initiation net, explosion uses emulsion, manual charging's method powder charge.
Further, ventilation process is used in blast area in step (4), is preferably divulged information using mechanical forced.
Further, the ventilation of described mechanical forced is by Leads to new breeze explosion in the auxiliary ventilation blower of fanning of fresh wind port installation
Area, in lower air port, installation air exhauster, which extracts waste air out, drains into returnairshaft.
The present invention uses ventilation condition, accelerates the mass rate of emission of waste air.
Further, supporting is that gunite concrete is carried out while tunnel and adit digging in step (5).
The supporting in driving, needs to carry out concrete spraying support in time behind tunnel and adit digging, prevents peripheral rock from emitting
Fall, safeguard stability of the roadway.
Further, the depth of groove is 3~5m in step (6).
Groove in the present invention is that the characteristic of easy avalanche, the induction of progress part are put built on the sand in itself using broken nugget
Top, i.e. the medium-length hole ultra-deep 3-5m in nugget both sides arrangement, artificially form groove, accelerating top board natural caving.
Compared with prior art, beneficial effects of the present invention are：The present invention is quick-fried using long and medium hole drilling, millisecond difference detonator
The method back production difficulty mining blocks for ore deposit of declining, realize the back production of difficult mining blocks, have reclaimed mineral resources to greatest extent, improve
Back production efficiency, and this method does not need artificial and equipment to enter exploiting field, safe and reliable, simple and easy, advanced technology.
