Description
Technical field
The utility model relates to underground gob side entry retaining filling technique fields, and in particular to a kind of gob side entry retaining flexible filling
Bag.
Background technique
Coal mine is to solve excavation replacement anxiety, realizes without coal pillar mining, improves resource recovery, largely uses gob side entry retaining
Technology can also be achieved the ventilation of working face Y type by gob side entry retaining, solve the problems, such as corner gas exceeding limit in highly gassy mine.Gao Shui
Filler edge air gallery technology due to mechanization degree height, it is at low cost, connect top effect it is good, in recent years by largely be applied to coal
In mine production practices.During application, the engineers and technicians in the field by ZL201020535727.7,
The scheme device very good solution mentioned in ZL201020530078.1, ZL201010282345.2 and ZL201320802860.8
Obturation under the conditions of the Complex Roofs such as top plate is uneven, inbreak and the string bag is difficult to the problems such as connecing top, molding difference, preferably realizes
Using flexible filling bag quickly construct road-in packing.But it finds in practice process, is contacted in continuous two filled walls
Part, closed goaf effect is bad, and in highly gassy mine, this position is easily caused goaf gas to gush out into lane, caused
Local gas transfinites in lane, influences Safety of Coal Mine Production.
Utility model content
The purpose of the utility model is to provide a kind of gob side entry retaining flexible filling bags, can effective closed goaf.
To achieve the above object, the technical solution adopted in the utility model is as follows: a kind of gob side entry retaining flexible filling bag, packet
Filling bag ontology is included, the filling bag ontology is the cuboid of inner hollow, on each edge of the filling bag ontology uniformly
Multiple bands are disposed with, are respectively equipped with injected hole, filling bag ontology edge on four corners of the filling bag bodies top
Two sides of width direction are respectively equipped with the supplement bag being connected to filling bag ontology, the supplement bag over and under and filling
Bag ontology junction is filled bag bodies top 200mm, is filled this body side surface of bag using suture connection, supplement bag top distance
The width of aperture is 90-110mm.
Preferably, the equivalent width of the front and rear width of the supplement bag and the filling bag ontology.
Preferably, the filling bag ontology and supplement bag are all made of flame-retardant and anti-static air duct fabric and sew.
Preferably, the spacing between the adjacent band is 80-100cm.
Compared with prior art, the utility model has the following beneficial effects:
1, the utility model can be fully engaged top plate to abundant closed goaf Liu Xiang, eliminate goaf gas and pour in
In lane, lead to the potential danger that local gas transfinites in lane；Air in lane can also be blocked simultaneously and gushes out goaf, eliminate goaf
The security risk of spontaneous combustion of remaining coal；
2, deft design, structure are simple, facilitate installation, saving of work and time；
3, the filling bag of different size can according to underground mining concrete condition, be made to meet live requirement, effectively
Lane filling effect is stayed in guarantee.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is that highly gassy mine goaf is not filled by schematic diagram；
Fig. 3 uses schematic diagram for the utility model；
In figure, 1- fills bag ontology；2, band；3, injected hole；4, bag is supplemented；5, the closed not firm area in top is met.
Specific embodiment
The utility model is described in further detail in the following with reference to the drawings and specific embodiments.
As shown in Figure 1, a kind of gob side entry retaining flexible filling bag, including filling bag ontology 1, the filling bag ontology 1 is interior
The hollow cuboid in portion, is sewed using flame-retardant and anti-static air duct fabric, and length, width and height are determined according to live requirement；
Multiple bands 2 are evenly arranged on each edge of the filling bag ontology 1, band 2 is stitched using two cloths
It makes, the spacing between the adjacent band 2 is 80-100cm；
It is respectively equipped with injected hole 3 on four corners at the filling bag ontology 1 top, when slip casting selects the note at highest point
Slurry hole 3 carries out intubation slip casting, and the injected hole 3 at the second high point is selected to be exhausted, and it is anti-that two injected holes 3 of residue are fastened tie-down
Leak-stopping slurry；
Two sides of the filling bag ontology 1 in the width direction are respectively equipped with the supplement bag being connected to filling bag ontology 1
4,4 over and under of supplement bag is connected with filling 1 junction of bag ontology using suture, and the 4 top distance of supplement bag is filled
Fill out 1 top 200mm of bag ontology, filling 1 lateral opening hole width of bag ontology is 90-110mm, preferably 100mm, supplement bag 4 using with
The equivalent width of bag ontology 1 is filled, length is that the flame-retardant and anti-static air duct fabric of 1.5m sews, and supplement 4 side of bag uses wind
Cylinder cloth suture.
Traditional high water filling material filling bag will appear during slip casting meets the closed not firm area 5 in top as shown in Figure 2, in height
Gaseous mine, this closed not firm area 5 be easy to cause goaf gas to pour in lane, local gas in lane are caused to transfinite；In coal seam
It is easy the mine of spontaneous combustion, this closed not firm area 5 be easy to cause air in lane to gush out goaf, leads to spontaneous combustion in goaf, give
Safety of Coal Mine Production brings great hidden danger, and the utility model flexible filling bag can effectively solve problems.
Use process is as follows: 1, according to field condition make the filling bag of suitable dimension；2, float coal is cleared up, monomer liquid is set
Pillar is pressed, steel mesh, hanging filling bag are connected；3, suitable injected hole and gas vent is selected to carry out slip casting, during slip casting,
When note to side supplements bag position, slurries flow into side and supplement bag, and the closed not firm area of tradition filling bag filling appearance is filled
Full, filling effect is as shown in figure 3, can effective closed goaf after filling.
