The invention discloses a gob-side roadway retaining method based on roof
cutting of a soft roof plate. According to the gob-side roadway retaining method based on roof
cutting of the soft roof plate, a movable stop lever air leakage preventing device is used for assisting in roadway formation, so that roadway formation achieved by filling walls with concrete in the prior art is replaced; the adopted stop lever air leakage preventing device is an
assembly, and the whole stop lever air leakage preventing device is of a square tubular structure and comprises an upper cap plate, folding air cloth, a single hydraulic prop, a steel
wire mesh and a lower shoe plate; the steel
wire mesh is hung on the side close to a gob; and the folding air cloth is fixed to the side close to a roadway. The stop lever air leakage preventing device and a working face advance to be dismounted and mounted synchronously and can be moved to another place to be used again, after the stop lever air leakage preventing device is dismounted and moved, liquid concrete is sprayed onto a wall formed by rocks exposed out of one side of the stop lever air leakage preventing device, and a series of technique means such as gap blocking and sealing are adopted, so that compared with a gob-side roadway retaining method in the prior art, the gob-side roadway retaining method based on roof
cutting of the soft roof plate has the beneficial effects that the roadway forming speed is high, the efficiency is high, the safety performance is good, the concrete filling work amount is small, and the cost is low.
