Abstract
The invention discloses a closed type capping method by upward filling mining. The method is characterized in that after stoping the last layer, four gas vent holes are drilled in four side corners of a roof by use of a drilling machine, and then, partition walls are built at the periphery of a mined-out area for processing the bottom of the mined-out area and the roof to be flat; waterproof materials are paved and pasted on the partition walls at the periphery of the mined-out area, the bottom of the mined-out area and the roof for enclosing the mined-out area into a closed type filling space; by virtue of a filling raise, a filling material is injected into the closed type filling space; when the filling material runs out of the gas vent holes, filling is stopped; and after the closed type filling space is filled up with the filling material, a layer of waterproof materials covers the four gas vent holes and the filling raise, and cement is used for sealing. The closed type capping method prevents water in filling slurry from discharging, and keeps the volume and the shape of the filling slurry; after the filling material is condensed, a completely roof-contacted filling body is formed, so that a filling roof-contact problem is solved. The closed type capping method is simple in process, safe and reliable, simple and easy to perform, and relatively low in cost.
Description
Technical field
The invention belongs to underground mining method technical field, to the closed method for capping of mining with stowing on especially a kind of.
Background technology
The mode that underground mining method is safeguarded by ground pressure is divided into openstope method, filling method and caved stopes three major types.
Mining with stowing artificial supporting mining codes owned by France.In mineral building or nugget, along with the propelling of stope, send into filler to goaf, to carry out underground pressure management, to control country rock avalanche and surface movement, and carry out back production in the obturation formed or under its protection.This law is applicable to exploit the ore body of weak-walled high-grade, rare, precious ore; Earth's surface does not allow to subside, and mining conditions is complicated, as the ore body below water body, trunk railway, key construction and the ore body etc. having freely burning fire danger, and the effective measures of pressing with controlling when being also deep mining.The advantage of filling method is strong adaptability, ore recovery rate is high, the rate of dilution is low, operation is safer, can utilize industrial waste and protection earth's surface etc.
In the method for mining by the way of filling, upward filling method application is very extensive, and mineral building or nugget are divided layering by upward filling method in vertical height, from bottom to top successively back production.In nugget, arrange fill pass, be used for transferring casting resin, sometimes double as fortune equipment of carrying, material, ventilation and pedestrian and use.Often adopt a layering, carried out filling immediately, and in obturation, construct ore chute and pedestrain raise (doubling as drainage sump to use) by the way.Exploitation process is rock drilling, ore caving, ore removal, erection pedestrain raise and mine chute, construction partition wall, filling and bedding fan-shaped pushing etc.At the fan-shaped pushing that each slicing and filling body top equal bedding intensity is larger, the dilution of ore and loss during to reduce ore removal also improve ore removal efficiency.Build partition wall near ore pillar, loose fill and ore pillar are separated, for next step stooping pillaring creates good condition.
Filling mainly contains dry stowing and consolidated fill, and dry stowing refers to and adopts loose waste fill goaf, and consolidated fill is that bottom adopts high cement-sand ratio, and top adopts low cement-sand ratio to carry out consolidated fill.Tight filling is that each uses the technical problem of the mine extensive concern of the method for mining by the way of filling, and it is directly connected to Stope safty.Tight filling amount number with connecing top rate to represent, i.e. the obturation contact area of top board and the ratio of whole top board area.The top rate that connects improving filling is the key technology difficult problem that the method for mining by the way of filling needs to solve, and relevant Tight filling problem fails to be well solved all the time.
There is much research in this respect at present, research filler in the majority, and compared with traditional dry stowing or sand-lime consolidated fill, adopted high-moisture quick-setting cementitious materials to play a role improving in Tight filling effect.But connecing in the practice of top, the slurries that high-water material mixes with water are before rapid hardening, a large amount of free water and free water-clogged slurries are due to infiltration and directly discharge, and are originally full of the liquid level of slurry decline in goaf, cause to connect top and do not go up, obturation solidifies upper back easy-weathering, and filling effect is unsatisfactory.
Summary of the invention
The object of this invention is to provide in one to the closed method for capping of mining with stowing.
The object of the invention is to be realized by following technical proposals.
To the closed method for capping of mining with stowing on a kind of, the method is by nugget horizontal division layering in vertical height, successively back production from bottom to top, often adopt a layering, carry out filling immediately, and ore chute and pedestrain raise (8) is constructed by the way in each slicing and filling body (4), fill pass (6) is arranged in nugget, fill pass (6) is utilized to transfer casting resin and carry fortune equipment, material, personnel and ventilation, exploitation process comprises rock drilling, ore caving, ore removal, construct ore chute and pedestrain raise (8) in addition, partition wall (3), filling and bedding fan-shaped pushing, described partition wall (3) is built near ore pillar, loose fill and ore pillar are separated, it is characterized in that when after back production last layering complete, rig is utilized to get four steam vents (10) at top board (5) four edges, again in goaf surrounding building partition (3), process smooth by bottom goaf with top board (5), at the partition wall (3) of goaf surrounding, with top board (5) above paving waterproofing materials (9) bottom goaf, waterproofing materials is not pasted in steam vent (10) and filling well (6) position, partition wall (3), a closed filling space (7) is surrounded with top board (5) bottom goaf, by fill pass (6), filler is injected closed filling space (7), when filler overflows steam vent (10), stop injecting, after filler fills closed filling space (7), again by four steam vents (10) and fill pass (6) upper covering one deck waterproofing materials, and seal with cement.
Described filler is the mixed solution of high-moisture quick-setting cementitious materials and water; Described waterproofing materials is SBS waterproof roll.
The diameter of described fill pass (6) is 1000-2000mm, and the aperture of steam vent (10) is 60-150mm; Described partition wall (3) thickness is 100-200mm.
The present invention compared with prior art, its significantly beneficial effect be embodied in: last layering goaf surrounding and top, base plate are sticked waterproofing materials by the present invention, make it formation closed filling space, again filler is injected closed filling space, prevent the discharge of water in filling slurries, keep volume and the shape of filling slurries, after condensation of materials to be filled, form the obturation that connects top completely, thus solve Tight filling problem.Present invention process is simple, and safe and reliable, simple, cost is lower.
