Abstract
The utility model relates to a kind of down-hole gob-side entry retaining support bag.After the inner chamber of bag is full of, be cuboid, fix the fixing noose of multiple anchor poles on the external surface of bag, there is the import and export communicating with the inner chamber of bag the upper end of bag, on the inner chamber left and right wall of described bag, fixes left and right stay cord.It is simple in structure, is out of shape littlely, and error is little, and filler consumption is few.
Description
Technical field
The utility model relates to a kind of supporting installation in underground mining, particularly the supporting bag of down-hole gob side entry retaining.
Background technology
After coal mining, for preventing subsidence, carry out filling.Underground filling mainly adopted hydraulic filling in the past, and its shortcoming is that charges do not connect top, and speed is slow simultaneously, and energy consumption is large, and operation is also inconvenient, causes the coal under down-hole coal column, square, under railway, under highway, under building not exploit.Along with state coal resource exploitation dynamics continues to increase, resource is fewer and feweri, there is a lot of collieries resource to approach exhausted, adopt at present the new placement method of baffle plate and plastics combination, new fill method can recovery well under coal under coal column, square, under railway, under highway, under building, extend the colliery length of service, increased output, reduced cost.New placement method has that filling velocity is fast, filling real, do not subside, and the advantage of energy conservation.But new filling method mainly uses baffle plate, plastics in conjunction with filling, inconvenient operation, often leaks material, and what make casting resin spray is everywhere, solidify rear very bad cleaning, even block whole production face, it is very difficult to deal with, impact exploitation output, has also increased labour intensity, has improved cost of production
Summary of the invention
In order to overcome the shortcoming of prior art, the utility model provides a kind of down-hole gob-side entry retaining support bag, and it is simple in structure, is out of shape littlely, and error is little, and filler consumption is few.
The technical scheme in the invention for solving the technical problem is: after the inner chamber of bag is full of, be cuboid, on the external surface of bag, fix the fixing noose of multiple anchor poles, there is the import and export communicating with the inner chamber of bag the upper end of bag, on the inner chamber left and right wall of described bag, fixes left and right stay cord.
The utility model is simple in structure, is out of shape littlely, and error is little, and filler consumption is few.
Brief description of the drawings
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is the utility model the first embodiment axonometric drawing;
Fig. 2 is the utility model the second embodiment axonometric drawing;
Fig. 3 is the utility model the 3rd embodiment axonometric drawing.
Detailed description of the invention
As shown in Figure 1, after the inner chamber of bag 4 is full of, be cuboid, on the external surface of bag 4, fix the fixing noose 2 of multiple anchor poles, there is the import and export 1,3 communicating with the inner chamber of bag 4 upper end of bag 4, on the inner chamber left and right wall of described bag 4, fixes left and right stay cord 5.Can reduce bag 4 left and right distortion.
Stay cord 6 before and after fixing on the inner chamber front and rear wall of described bag 4.Can reduce bag 4 front and back distortion.
On about inner chamber of described bag 4, front and rear wall, be fixed with respectively left and right stay cord 5, front and back stay cord 6.
Described left and right stay cord 5 and front and back stay cord 6 have respectively many.As shown in Figure 2.
On the inner chamber left and right wall of described bag 4, fixing left and right draws in the net 7.As shown in Figure 3.
Before and after fixing on the inner chamber front and rear wall of described bag 4, draw in the net 8.
On the inner chamber left and right wall of described bag 4 and front and rear wall respectively fixing left and right draw in the net 7 and front and back draw in the net 8.
