Description
Technical Field
The utility model belongs to the technical field of the tunnel is backfilled, concretely relates to go up mountain tunnel preformed hole filling system.
Background
According to the national environmental protection requirement and treatment planning, the situation that the existing waste rock is not treated to reach the standard in 2022 years, and all the waste rocks which cannot be used in a newly-built mine are returned to the mine is realized, the yield of the waste rocks of about 45 million tons in the mine of the unit of the application is about in the bottom suction roadway every year, and according to the green filling planning of the mine, the waste rocks of the bottom suction roadway can be filled to the abandoned bottom suction roadway by using a pipeline by using a pumping waste rock filling technology after the waste rocks of the bottom suction roadway are crushed and stirred. At present, the domestic roadway filling technology is mainly researched for the filling of a downhill roadway, and when the uphill roadway is filled, because the crushed and stirred gangue slurry is filled in the uphill roadway and is difficult to block, the filling of the uphill roadway is difficult to realize in many mines, and the technology is a blank in domestic technology.
The working surface topography of the north wing of a five-panel mine excavated by the unit of the application is north high, south low, and most of tunnels are excavated in the upward direction; the existing mine bottom suction roadway waste rock filling system is characterized in that waste rocks are crushed and stirred and then conveyed to a waste bottom suction roadway through a pipeline by using a high-pressure pump, and due to the fact that a north-wing roadway of a five-panel area is used for driving upwards, waste rock slurry conveyed through the pipeline is difficult to block in the upwards driving roadway, and the mine upwards driving bottom suction roadway cannot be filled.
SUMMERY OF THE UTILITY MODEL
The utility model discloses to the great tunnel of the excavation slope of going up a hill in the pit, solve the problem that the tunnel of going up a hill is difficult to realize the slip casting and fills.
In order to realize the above-mentioned purpose, the utility model provides an upward hill tunnel preformed hole filling system lays the grout in the coal seam tunnel parallel with the target end suction lane and is responsible for, the grout is responsible for the high-pressure pump on the UNICOM's well, the concrete wall body that prevents the descending of fluid has been arranged to the subsection in the target end suction lane, leave the clearance between concrete wall body and the target end suction lane roof, the target end between two concrete wall bodies takes out the tunnel roof in the construction have with the wearing layer hole of coal seam tunnel intercommunication, the downthehole interlude of wearing layer has the lateral conduit, the lateral conduit is responsible for the UNICOM with the grout.
Furthermore, a gap with the width of 20-30 cm is reserved between the concrete wall and the target bottom suction roadway top plate.
Compared with the prior art, the utility model has the advantages that:
the utility model provides a pair of go up mountain tunnel preformed hole filling system reserves wearing layer hole through the construction pipeline in advance in the target bottom suction lane roof to build concrete wall in the target bottom suction lane tunnel, solved go up mountain abandonment bottom suction lane fill slurry and be difficult to the difficult problem that shutoff and bottom suction lane abandonment back personnel can't get into.

In addition, "perpendicular" includes not only mutually perpendicular in which two objects are directly connected in space but also mutually perpendicular in which two objects are not connected in space.
As shown in fig. 1 and 2; a filling system for reserved holes of an uphill roadway comprises a grouting main pipe 4 laid in a coal seam roadway 3 parallel to a target bottom suction roadway 7, a high-pressure pump communicated with a shaft is arranged in the grouting main pipe 4, a concrete wall body 1 for preventing fluid from descending is arranged in the target bottom suction roadway 7 in a segmented mode, a gap is reserved between the concrete wall body 1 and a top plate of the target bottom suction roadway 7, a layer penetrating hole 5 communicated with the coal seam roadway 3 is constructed in the top plate of the target bottom suction roadway 7 between the two concrete wall bodies 1, a branch pipeline 6 is inserted in the layer penetrating hole 5, and the branch pipeline 6 is communicated with the grouting main pipe 4.
And a gap with the width of 20-30 cm is reserved between the concrete wall 1 and the top plate of the target bottom suction roadway 7.
The utility model discloses a during the use is taken out the tunnel tunnelling at the bottom of going up, through taking out tunnel roof construction wearing layer hole 5 and upper portion coal seam tunnel 3 at the bottom and lining up, pre-buried laying branch pipeline 6 in advance, and according to the tunnel slope situation of change of going up, concrete wall 1 is built in segments, treat the airtight back of bottom and take out tunnel abandonment, be responsible for 4 through laying the grout in coal seam tunnel 3, be responsible for 4 interface connections to the pipeline in preformed hole with the grout, the waste rock slurry after will breaking the stirring, the tunnel of going up is filled to the segmentation, realize the filling of waste rock tunnel of going up, reach the mine waste rock and backfill, the purpose of green filling.
