Erecting method of underground roadway filling pipeline

Abstract

The invention relates to an erecting method of an underground roadway filling pipeline. The erecting method is characterized by comprising the following steps that (1) the height from a filling pipeline to a bottom plate of a roadway is determined; (2) a row of anchor rods are preset on a vault of the roadway at equal intervals in the flowing direction of slurry in the filling pipeline, a pipelinehanging bracket pull rod is arranged at the lower ends of the anchor rods in a welded mode, a tail ring is arranged at the lower part of the pipeline hanging bracket pull rod in a welded mode, and the upper ends of the anchor rods are anchored on the vault of the roadway through cement mortar; and (3) the filling pipeline is composed of a plurality of pipe sections, each section of filling pipeline is connected with an upstream filling pipeline by adopting a clamp type connector, pipe clamping clamps are arranged in the middle of each section of filling pipeline, and the pipe clamping clampsare fixedly connected with the tail ring of the hanging bracket pull rod through a bolt, a gasket and a nut until the tail end of the filling pipeline in a filling stope is reached. The erecting method of the underground roadway filling pipeline has the advantages that the pipeline is convenient to mount and dismount, the width and the sectional area of a roadway can be reduced, the engineering quantity is saved, and the local resistance of filling slurry conveying can be further reduced.

Description

technical field [0001] The invention relates to a mine mining and filling system, in particular to a method for erecting an underground roadway filling pipeline auxiliary for mine filling. Pipeline transportation of filling slurry. Background technique [0002] At present, underground filling pipelines in mines are mostly laid along the roadway floor or erected along the side wall of the roadway. When the pipeline satisfies the safe passage of vehicles and personnel, the width of the roadway is relatively large, and the arch height is proportional to the width of the roadway. Therefore, it will inevitably lead to a larger section of the roadway, which will increase the amount of roadway excavation and support works, especially when the filling pipeline is erected along the side wall of the roadway. Both conflict with the position of the filling pipeline, so the filling pipeline needs to be erected on the side wall of the roadway on the opposite side of the pressure air and ...

[0002] At present, underground filling pipelines in mines are mostly laid along the roadway floor or erected along the side wall of the roadway. When the pipeline satisfies the safe passage of vehicles and personnel, the width of the roadway is relatively large, and the arch height is proportional to the width of the roadway. Therefore, it will inevitably lead to a larger section of the roadway, which will increase the amount of roadway excavation and support works, especially when the filling pipeline is erected along the side wall of the roadway. Both conflict with the position of the filling pipeline, so the filling pipeline needs to be erected on the side wall of the roadway on the opposite side of the pressure air and water supply pipes, resulting in further enlargement of the roadway section

At the same time, along the roadway along the vein that the main horizontal main filling pipeline passes through, it needs to cross many chambers connecting roadways or branch roadways, so the filling pipeline needs to cross the door frequently. , the slurry in the pipeline between the two convex cross-doors is easy to deposit; on the contrary, when the lower-span door is used, the filling pipe becomes concave, which also greatly increases the local resistance, and the slurry in the pipeline at the concave cross-door is easy to deposit , and the pipeline at the concave cross door has the risk of being damaged by vehicles and people

In addition, when the filling pipeline is laid along the roadway floor, it is not easy to detect the leakage of the pipeline during the inspection
