Description
Technical field
The present invention relates to the filling forming structure that a kind of filling mining or gob side entry retaining use, especially a kind of coal mine
Retrofilling bag shaped structure and its application method.
Background technique
In mineral industry, for filler carry out gob side entry retaining, the country use at first activity steel form as
Construct thereafter as the raising of technology uses flexible filling bag instead as construct, and carries out gob side entry retaining by high-water material
Flexible filling bag is all made of in the ultrahigh water material goaf filling method of reference as filling construct.
Field engineering practice in using flexible filling bag carry out filling construct after, formed obturation can be with lane
The effect of road roof and floor pressure and expand deformation so that final filling effect is not satisfactory, and use flexible filling
Bag needs to formulate the size of filling bag, ununified standard model, so that scene is applied according to the field condition of each coal mine
Work takes a long time.
Summary of the invention
In order to overcome the shortcomings of the prior art, the present invention provides a kind of underground coal mine filling bag shaped structure and its use
Method, the filling bag shaped structure itself has intensity and model standardizes, and expense can be speeded up the work and be reduced to application method
With.
The technical solution used to solve the technical problems of the present invention is that:
A kind of underground coal mine filling bag shaped structure, including girder truss wall, filling bag shaped structure surface encapsulation layer and bottom
Portion's structure, the girder truss wall are formed by girder truss is framework superimposed, and the girder truss frame is completely the same by four sides
Girder truss aggregate head and the tail be formed by connecting, every row's girder truss aggregate is by multiple girder truss cell cubes connected shape arranged in parallel
At the bottom of the girder truss cell cube is rectangle, and top is surrounded by four triangles, and four vertexs of a triangle are overlapped
For a bit, and subpoint of this on the rectangle of bottom surface is two cornerwise intersection points of rectangle, and two of triangular base
Vertex is successively overlapped with four vertex of rectangle, and rectangle only connects a diagonal line, and the rectangle of adjacent truss beam element body is diagonal
Line connection is opposite；Girder truss wall is fixedly connected on inner surface sealant and the outer surface of filling bag shaped structure surface encapsulation layer
Between sealant, while girder truss wall is mounted on bottom structure.
A kind of application method of underground coal mine filling bag shaped structure, including following operating procedure: 1) it is needing using filling
At the down well placement of bag shaped structure, ground is flattened, then steadily places bottom structure；2) truss is coupled on bottom structure
Beam aggregate successively sets up a circle girder truss aggregate and forms girder truss frame, is superimposed multiple girder truss frames and eventually becomes one
Stifled girder truss wall；3) it when the height of girder truss wall reaches and contacts with roof, injects and fills at preset inlet
Filling chock material is completed after material solidification to be filled.
Compared with prior art, a kind of underground coal mine of the invention filling bag shaped structure and its application method, due to its filling
Bag shaped structure is formed by girder truss cell cube set, and specifically, girder truss cell cube constitutes girder truss aggregate, then by purlin
Aggregate of setting a roof beam in place forms girder truss frame, and final girder truss is framework superimposed at girder truss wall, and girder truss wall is arranged in bag
It in shape body structure surface sealant and is mounted on and just constitutes filling bag shaped structure of the invention on bottom structure, injection is filled thereto
Filling chock material, the girder truss cell cube can generate outside expansionary force in top (i.e. internal) active force by obturation,
In girder truss wall under the anchor pole of horizontal drawing or the stretching action of anchor cable, so that giving internal one outside girder truss cell cube inwardly
Reaction force effect, power between the two cancels out each other, and the final filling forming structure can effectively control obturation
The dilatancy of the lower filling forming structure generated of compression power effect.As it can be seen that the present invention is that itself has intensity and type
Number standardized convenient filling forming structure, so that for underground gob side entry retaining and the more universalness and height of filling mining technique
Using for effectization provides convenience, and can reduce expense of colliery industry when with process above.
