Abstract
The invention discloses a construction method of a gob-site entry retaining wall of solid filling coal mining. The retaining wall is composed of a gangue-piled wall and a compact cementing filling body. The construction method comprises the following steps: cleaning float coal close to an end head after mining and removing frame at a working face; arranging a row of single supporting columns at inner side of a roadway, close to a gob; arranging a wooden backboard at the gob side, close to the single supporting columns; connecting the backboard with the top and bottom; fixing the backboard to the single supporting columns through iron wires; piling the gangue wall at the gob side, close to the backboard; filling the gangue and cement mixing filling material into the gob at the back of two brackets of the gangue-piled wall after the gangue wall is piled; compacting through a rammer compactor to form the compact cementing filling body. With the adoption of the method, the recovery ratio of coal resources can be raised; in addition, the operation at the filling working surface is simple and convenient to carry out, and is also safe and reliable, and high practicability is also brought.
Description
Technical field
The construction method that the present invention relates to a kind of solid filling coal mining gob-side entry retaining support body of wall, is particularly useful for solid filling coal-face without coal column gob side entry retaining.
Background technology
In recent years, solid filling coal-mining technique is progressively ripe, in China's railways and water-bodies, is widely used, and has obtained significant economy, society and environmental benefit.Goaf is enriched rate and can be reached more than 85%, and because goaf has been filled with solid filling material, the movement and deformation degree of overlying rock significantly reduces, and substantially presses and manifests without ore deposit.Under normal circumstances, between two work planes of the upper and lower section of filling coal mining, stay the coal column of establishing 20m left and right, caused a large amount of coal resources losses.In order further to improve recovery ratio, most mines have adopted edge air gallery technology, but its gob-side entry retaining method is to carry out on the basis based on caving method exploitation, and difficulty of construction is large, and cost is high, and construction technology and work plane filling influence each other, inefficiency.
Summary of the invention
Technical problem: the object of the invention is to overcome the weak point in prior art, a kind of construct simple, cost is low, efficiency is high solid filling coal mining gob-side entry retaining support body of wall and construction method thereof are provided.
Technical scheme: solid filling coal mining gob-side entry retaining support wall construction method of the present invention, comprises the steps:
A. work plane is cleared up near the float coal in termination after mining, move frame, then in tunnel, is close to goaf side and sets row's individual prop;
B. be close to individual prop and install wooden backboard at goaf side, at the bottom of backboard connects apical grafting, utilize iron wire that backboard is fixed on individual prop;
C. at goaf side, be close to backboard and assemble to form and assemble pack wall by filling up the common woven bag of spoil or snakeskin bag;
D. after assembling pack wall and finishing building into, cement spoil compound is transported on the stowage conveyer that is suspended on back timber below after support by self-moving reversed loader, by stowage conveyer by cement spoil compound transport, unload and drop down onto near assembling goaf, back timber below after two supports of pack wall, utilize rammer compacter repeatedly to tamp, form closely knit cemented fill, complete the operation of gob-side entry retaining support wall construction.
In described tunnel next-door neighbour to adopt the individual prop spacing that sky side sets be 0.6～1.0m; The described width that assembles pack wall is 1.5～2.0m.
Beneficial effect: solid filling coal mining gob-side entry retaining support body of wall of the present invention and construction method thereof, can improve the rate of extraction of coal resources, save tunnelling expense, can solve again the problem of methane accumulation simultaneously, method is simple, easy and simple to handle, cost is low, has important practical significance and wide application prospect.Compared with prior art there is following advantage:
1) filler from on-the-spot, cost is low, reduced down-hole assistant conveyance amount;
2) assemble the movement and deformation that pack wall and closely knit cemented fill can adapt to top board well;
3) construction technology combines with goaf filling technique, and efficiency is high.

Detailed description of the invention
Below in conjunction with accompanying drawing, one embodiment of the present of invention are further described:
As shown in Fig. 1～4, solid filling coal mining gob-side entry retaining support body of wall of the present invention is by the Mixed support body that assembles pack wall 4 and closely knit cemented fill 5 and form, assemble pack wall 4 and be by filling up the common woven bag of spoil or snakeskin bag and assemble and form, closely knit cemented fill 5 is to be formed after compacting by cement spoil compound, the construction method of described solid filling gob-side entry retaining support body of wall, concrete steps are as follows:
A. work plane is cleared up near the float coal in termination after mining, move frame, then in tunnel, sets row's individual prop 1 near goaf side, and individual prop 1 spacing is generally 0.6～1.0m;
B. be close to individual prop 1 and install wooden backboard 2 at goaf side, at the bottom of backboard 2 connects apical grafting, utilize iron wire 3 that backboard 2 is fixed on individual prop 1;
C. at goaf side, be close to backboard 2 by fill up the common woven bag of spoil or snakeskin bag assemble form the wide 1.5～2m of being assemble pack wall 4;
D. after assembling pack wall 4 and having assembled, cement spoil compound is transported to by self-moving reversed loader 6 on the stowage conveyer 7 that is suspended on back timber 8 belows after support, by stowage conveyer 7 by cement spoil compound transport, unload and drop down onto near assembling back timber 8 goafs, below after two supports of pack wall 4, utilize rammer compacter 9 repeatedly to tamp, form closely knit cemented fill 5, complete the operation of gob-side entry retaining support wall construction.
