Example Embodiment

[0009] The anti-leakage roof of the working face is composed of pillars 1 arranged at intervals and beams 2 erected on pillars 1. The bottom of the pillars 1 is fixed on the bottom of the roadway, and the beams 2 are fixedly arranged on the top of pillar 1. Filling stacks 3 are filled between the side facing the sidewall of the roadway and the pillar 1, which is characterized in that: the upper side of the cross beam 2 faces the roof 4 of the roadway, and the filling is filled between the cross beam 2 and the roof 4 物5.

[0010] The present invention also designs a layer of Malisan covered between the filler 5 and the top plate 4.

[0011] The present invention also designs that the cross beam 2 is a steel beam or a wooden beam.

Abstract

The invention relates to a leakage-proof stope face roof comprising supporting columns arranged at an interval and a beam erected on the supporting columns. The bottoms of the supporting columns are fixed on a tunnel bottom plate, the beam is fixedly arranged at the tops of the supporting columns, a filling buttress is filled between one side, facing the side wall of a tunnel, of one supporting column and the supporting column, the upper side of the beam faces a top plate of a tunnel, and fillers are filled between the beam and the top plate. The stope face protection roof is capable of improving supporting quality and guaranteeing stoping safety, cohesive force and an internal friction angle between a fracture and a coal-rock mass are increased by means of erecting a Malisan material layer, resistance of relative displacement between the inside of a rock mass and a stope face is increased, and integral stability of the coal-rock mass and stoping safety are improved.

Description

technical field [0001] The invention relates to equipment for coal mine exploitation, in particular to a leak-proof top plate of a mining working face. Background technique [0002] There are large cracks inside the coal rock mass and between the coal rock mass and the mining face in the current mining face, which makes the overall stability of the coal rock mass poor, and there is a great potential safety hazard when mining coal mines. Contents of the invention [0003] The present invention aims to provide a leak-proof top plate of a mining working face which is safe, reliable, reduces costs and saves coal resources. [0004] The technical solution of the present invention is: the leak-proof roof of the mining face is composed of pillars arranged at intervals and crossbeams erected on the pillars, the bottom of the pillars is fixed on the bottom plate of the roadway, and the crossbeams are fixed on the top of the pillars. Filling piles are filled between one side wall o...
