Abstract

The invention discloses a kind of mining environment reconstructing movable type pumping filling artificial ore pillar shrinkage stoping, it is ore pillar and mineral building by ore body division, ore pillar is exploited first with slicing and filling mining codes technique, and use movable type pumping filling system filling, form artificial ore pillar, and reserved People's Bank of China and device channels, carry out mining environment reconstructing;Then shrinkage method mining technology rooming is used, at the pre-pillar in the side of mineral building, the most pre-pillar of opposite side, utilize drop shaft as stope returnairshaft, the pre-pillar of disposable recovery after mineral building back production, goaf does not processes, artificial ore pillar support goaf, thus realize the purpose of Steeply dipping narrow deposits safe working.The present invention is especially suitable for underground metal mine without filling system, and the high-grade that roof rock relatively consolidates tilts or the exploitation of Steeply dipping narrow deposits, has ore loss ratio low, it is not necessary to build filling system, technique is simple, job safety and the few feature of required casting resin.

Description

Mining environment reconstructing movable type pumping filling artificial ore pillar shrinkage stoping
Technical field
The present invention relates to a kind of underground metalliferous mine shrinkage stoping, particularly relate to a kind of mining ring Movable type pumping filling artificial ore pillar shrinkage stoping is reproduced in border, it is adaptable to underground mine is without filling System, and the high-grade that relatively consolidates of roof rock tilts or the exploitation of Steeply dipping narrow deposits.
Background technology
For Steeply dipping narrow deposits, in traditional handicraft, many employing shallow hole shrinkage methods are exploited, ore deposit Body is divided into mineral building and ore pillar, and not filling after mineral building back production, by ore pillar roof supporting; Be additionally, since orebody thickness little, dispersion, build filling pipeline system difficulties, it is impossible to use fill Filling out mining codes, ore pillar is generally Permanent pillar, it is impossible to reclaim.Therefore, this technique also exists ore deposit The shortcomings such as stone loss rate height, poor stability.Especially when ore body built on the sand time, ore pillar is easily sent out Life destroys, collapses, and then causes goaf top plate inbreak, causes underground hazard.Fill as used Fill out mining codes, filling system construction investment height, filling process complexity can be brought the most again, dig up mine into This crosses the shortcomings such as height, reduces the economic benefit in mine.
Summary of the invention
The technical problem to be solved is to provide one in mine without having during filling system Have that ore loss ratio is low, job safety and the low mining environment reconstructing movable type pumping of mining cost Filling artificial ore pillar shrinkage stoping.
In order to solve above-mentioned technical problem, the mining environment reconstructing movable type pumping that the present invention uses Filling artificial ore pillar shrinkage stoping, exploits inclination or Steeply dipping narrow deposits and without filling system Time, according to stope structure size, ore body division is mineral building and ore pillar by across pitch direction, first Use overhand slicing mining technology exploitation ore pillar, and utilize movable type pumping filling system to enter Row slicing and filling operation, reserves People's Bank of China's inclined shaft and drop shaft during filling, carry out mining environment reconstructing; After and filling complete until pillar recovery forms artificial ore pillar, shrinkage method mining technology is used to carry out ore deposit The back production in room, at the pre-pillar in the side of mineral building with protection People's Bank of China inclined shaft, and in pre-pillar Dig People's Bank of China's connecting taxiway, personnel and equipment and enter stope operation by People's Bank of China's inclined shaft, connecting taxiway, The drop shaft of opposite side as stope returnairshaft, returnairshaft along with mineral building back production height rising and by Gradually avalanche;The pre-pillar of disposable recovery after mineral building back production, dead zone does not processes, by filling The artificial ore pillar that body is formed supports goaf.
The mining environment reconstructing movable type pumping filling artificial ore pillar using technique scheme stays Ore deposit mining codes, are ore pillar and mineral building by ore body division, first with upward ut and fill stoping Technique exploitation ore pillar, and utilize movable type pumping filling system filling, form artificial ore pillar, enter Row mining environment reconstructing;People's Bank of China's inclined shaft and drop shaft need to be reserved during filling, both can be that pillar recovery carries For passage, also provide People's Bank of China and vent passages for mineral building back production;Then shrinkage method getter is used Skill rooming, during mineral building back production, need to be at the pre-pillar in the side of mineral building, to protect People's Bank of China oblique Well, the pre-pillar of disposable recovery after mineral building back production, goaf does not processes, by people's industrial and mineral Post supports goaf.Thus in mine without filling system time, reach reduce ore losses, improve Resource recovery, reduces the purpose of mining cost.
Ore pillar uses the exploitation of overhand slicing mining technology, and by movable type pumping filling system Filling, forms artificial ore pillar, carries out mining environment reconstructing, and required casting resin is minimum, it is not necessary to Build filling system.
Mineral building uses the exploitation of shrinkage method mining technology, at the pre-pillar in mineral building side, protects People's Bank of China Inclined shaft, and in pre-pillar, dig People's Bank of China's connecting taxiway;The drop shaft of opposite side then returns as stope Ventilating shaft, personnel and equipment complete ore deposit by operation in People's Bank of China's inclined shaft, People's Bank of China's connecting taxiway entrance stope Room back production, technique is simple.
The present invention is applicable to underground metalliferous mine without filling system, and the Gao Pin that roof rock relatively consolidates Position tilts or in Steeply dipping narrow deposits back production, it is achieved that technique is simple, job safety, needed for fill The purposes such as filler is few, and ore loss ratio is greatly reduced, and mining cost is low.
The invention has the beneficial effects as follows, use overhand slicing mining technology exploitation ore pillar, and Utilize movable type pumping filling system to carry out packing job, form artificial ore pillar;Then use and stay Ore deposit method mining technology carries out the back production of mineral building, does not processes after mineral building back production, by the filling bodily form The artificial ore pillar become supports goaf.Without building filling system, and required casting resin is minimum, Ore recovery ratio is high, and mining cost is low, and technique is simple, solves Steep Dipping Ore Body Extraction exploitation losses A difficult problem for rate height, poor stability, construction filling system difficulty.
