Abstract
The invention discloses a method for sealed type empty field mining subsequent filling. The method is characterized in that a filling patio is dug in a top plate, four exhaust holes are formed at the positions of four corners of the top plate by utilizing a drilling machine; partition walls are built around a goaf, a base plate and the top plate are treated to be flat; waterproof materials are laid on the partition walls around the goaf, the base plate and the top plate; a sealed filling space is defined by the artition walls, the base plate and the top plate; a filling material is injected into the sealed filling space through the filling patio; when the filling material overflows out of the exhaust holes, the injection is stopped; after the filling material fills the sealed filling space, the four exhaust holes and the filling patio are covered with a layer of waterproof material, and openings are sealed with cement. According to the method, the volume and shape of filling grout are maintained, a complete roof-contacted filling body is formed, and accordingly the goals of filling and roof contact are achieved.
Description
Technical field
The invention belongs to Mining Science And Technology of Underground Metal Mine field, particularly relate to a kind of closed barnyard mining afterwards filling method.
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.
At present, openstope method uses relatively extensive, and nugget, in exploitation process, is divided into mineral building and ore pillar by openstope method, and the first step is first dug up mine room, and second step is dug up mine post again.When rooming, stope goaf exists with spacious empty form, and safeguards with the steadiness of ore pillar and country rock itself.After mineral building has been adopted, timely stooping pillaring and process goaf.Process goaf generally adopts placement method, i.e. openstope method afterwards filling.
As can be seen from the feature of above-mentioned openstope method, the primary condition of application openstope method is that ore and country rock are firm, goaf-fixing time interiorly allows larger exposed area.The application of this kind of mining methods the earliest, the most extensive, also the most ripe technically.
Openstope method afterwards filling mainly contains dry stowing and consolidated fill, dry stowing refers to and adopts loose waste fill goaf, consolidated fill is that bottom adopts high cement-sand ratio, top adopts low cement-sand ratio to carry out consolidated fill, body to be filled reaches some strength, for roof safety and pillar recovery subsequently create conditions.Carry out the back production of adjacent back end afterwards again, back production is complete carries out non-cementing (as tailings) filling to ore pillar goaf again.
The afterwards filling in goaf, Tight filling is the key technology difficult problem needing 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.As: " non-ferrous metal (mine part) " 06 phase in 1996 " VCR method stope afterwards ' three-in-one ' filling and Percentage of Water Rapid Solidifying Material connects top " paper, once use " three-in-one " filling in goaf in large quantities and finally connect top with high water retaining quick-set, but in the end connect 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 also directly discharge, the former liquid level of slurry being full of goaf declines, cause and 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 a kind of closed barnyard mining afterwards filling method.
The object of the invention is to be realized by following technical proposals.
A kind of closed barnyard mining afterwards filling method, after the method adopts the complete mineral building of openstope method back production, form spacious empty goaf, it is characterized in that the upper cutting fill pass (6) of top board (5), transfer casting resin by fill pass (6) and carry fortune equipment, material, personnel and ventilation, rig is utilized to get four steam vents (8) at top board (5) four edges, in goaf surrounding building partition (3), base plate (10) and top board (5) are processed smooth, in goaf surrounding partition wall (3), base plate (10) and the upper paving waterproofing materials (7) of top board (5), waterproofing materials is not pasted in steam vent (8) and filling well (6) position, partition wall (3), base plate (10) and top board (5) surround a closed filling space (4), by fill pass (6), filler is injected closed filling space (4), when filler overflows steam vent (8), stop injecting, after filler fills closed filling space (4), again four steam vents (8) and fill pass (6) are covered 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 (8) is 60-150mm; The thickness of described partition wall (3) is 100-200mm.
The present invention compared with prior art, its significantly beneficial effect be embodied in:
Mineral building 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.
