Abstract
The invention relates to a separate type filling method of a goaf. A plurality of flexible filling bags are hung at longitudinal or transverse intervals along the propelling direction of a coal face in the goaf and a template supported by a single brace is erected outside the filling bags. Specifically, the method includes: filling high-water materials in the filling bags; after the high-water materials are coagulated, dismantling the template and the single brace to complete a row of separation bodies; advancing along the coal face and repeating the steps until the coal advances to reach the span separating the goaf; then building a row of transverse enclosed separation body walls, irrigating the high-water materials to the enclosed wall; then continuing the work repeatedly until the coal face finishes; subsequently building an enclosed wall in a transportation alley and a track alley; and conducting final filling to complete the filling work of the whole goaf. The method uses the enclosed separation body goaf, irrigates the enclosed goaf on the basis of no accidental fall of top plates. The filling method is simple, the equipment investment is low, the filling efficiency and filling compactness are high, the stability is good and the cost is low.
Description
Technical field
The present invention relates to a kind of separate type filling method of goaf, be applicable under the building, under the water body, railway down with water body on goaf filling behind the coal mining.
Background technology
For a long time, under the building, under the water body, railway caused the deformation failure on overlying rock and the face of land behind the coal mining down with on the water body, and lithic drainage is destroyed, above ground structure destruction is out of shape and is caused and can't use.Therefore, need carry out the rock stratum that filling slows down above goaf to goaf behind the coal mining and move downward, thereby reach the purpose on the protection face of land.
The main filling method in goaf has waste filling, hydraulic filling, lotion and paste-like backfill etc. at present.These filling methods have all played certain effect to the sinking control on the face of land.But waste filling, hydraulic filling because pack completeness is lower, filling cost is high, limited to the sinking control action on the face of land.Paste body filling and paste-like backfill complex process are invested greatlyyer, reach several ten million yuan, thereby have limited the application and the popularization of above-mentioned placement method.
Summary of the invention
Technical problem: the present invention seeks to overcome the deficiency of existing goaf filling technology, method is simple relatively, and filling cost is relatively low, and pack effectiveness is higher.This separate type filling method of goaf is the stronger goaf filling method of a kind of applicability.
Technical scheme: separate type filling method of goaf of the present invention:
A, in treating the goaf of filling along coal-face direction of propulsion, vertical or horizontal arrangement pitch distance L
1Or obstruct goaf span L
3Hang a plurality of flexible filling bag;
B, expose side in the flexible filling bag of hanging and arrange individual prop at interval;
C, set up the template that relies on individual prop in the flexible filling bag outside;
D, by Grouting Pipe filling high-water material in flexible filling bag, until full;
E, treat that high-water material solidifies after, stripping and individual prop are finished row's filling barrier bodies;
F, with the propelling of coal-face, vertically the filling barrier bodies of arranging continues to construct next exclusion spacer, continuous flexible filling bag, repeating step b, c, d, the e of hanging in a last exclusion spacer position, go round and begin again, intercept the goaf span L when the filling barrier bodies of constructing reaches
2The time, vertically and between the filling barrier bodies of vertically arranging constructing a horizontal row,,, finish the totally-enclosed of regional goaf until full by Grouting Pipe flood irrigation high-water material in enclosing wall to filling barrier bodies enclosing wall;
Transversely arranged filling barrier bodies reaches at interval and intercepts the goaf span L
3The time, construct next horizontal row to the enclosing wall filling barrier bodies of arranging, by Grouting Pipe flood irrigation high-water material in enclosing wall filling barrier bodies,, finish the totally-enclosed of regional goaf until full;
G, advance, continue to hang filling bag, repeat above-mentioned steps b, c, d with the continuation of coal-face, e, f goes round and begins again, until the flood irrigation operation with the goaf of constructing of finishing whole goaf barrier bodies;
H, construct enclosing wall, carry out unified at last filling in fortune lane and track lane, with the goaf not pack portion be full of, finish the packing job in whole goaf.
The length a of described flexible filling bag is 10m～20m, and width b is 2m～3m, and c is identical with the work plane mining height for height; The spacing distance L of flexible filling bag is hung in described vertical arrangement
1Be about 10m～25m, intercept the goaf span L
2Should be about 8m～30m less than the step pitch of directly pushing up or old top collapses for the first time and; Described transversely arranged obstruct goaf span L of hanging flexible filling bag
3Should be about 8m～25m less than directly top or the old top step pitch that falls that collapses for the first time.
Beneficial effect: by at the vertical or horizontal extension bag of goaf section construction, adopt high-water material to carry out filling then and form barrier bodies, obturation is solidified the back top board is supported, and reduces the absciss layer of top board.After barrier bodies reaches some, by Grouting Pipe to airtight goaf filling high-water material, until full.After treating that high-water material filling slurries solidify, the top board that the goaf is exposed out supports.At last, after working face mining equipment is taken out of, construct enclosing wall at Liang Xiang and carry out at last unified filling, it is closely knit exploit space integral body filling, finishes whole filling operation.The present invention utilizes barrier bodies to intercept the goaf, do not take place at top board under the prerequisite of inbreak institute's barrier region to be carried out flood irrigation, and the pack effectiveness height, remarkable to the sinking control action on the face of land.The high-water material water supply volume is big, and down-hole waste water can satisfy the requirement of filling water, can reduce part drainage underground expense, and placement method is simple, and equipment investment is few, pack effectiveness and pack densification height, and good stability has practicality widely.
