Roadway roof caving management device and method

Abstract

Provided are a roadway roof caving management device and a method. The device comprises a support vertical column, a support plate, a support rod assembly, a first anchor net and a second anchor net;the support rod assembly comprises an ejector pin, a push rod, a support sleeve, a flange disk, a lock nut and a bearing plate; the first anchor net is laid on a top plate of a caving area, the support rod assembly is installed between the first anchor net and the support plate, and the second anchor net is laid under the support plate. The method comprises the steps of cleaning falling gravels, laying the support vertical column and the support plate, anchoring and connecting both ends of the support plate and the side of a roadway, inserting the support rod assembly into a support sleeve insertion hole, and fixing by a bolt; laying the first anchor net above a top support plate, moving upwards the push rod vertically until the top support plate abuts against the top plate of the caving area, the first anchor net is pressed against the top plate of the caving area, and the first anchor net is anchored on the top plate of the caving area; the second anchor net is laid under the supportplate, the second anchor net is firstly pressed against the flange disk by the lock nut and the bearing plate, and then the second anchor net is anchored on the top plate of the roadway of the non-caving area.

Description

technical field [0001] The invention belongs to the technical field of roadway support, and in particular relates to a roadway roof fall control device and method. Background technique [0002] At present, the roof fall control methods of the excavation working face mainly include the wedge method, the wood pile treatment method and the anchor shotcrete support method. The protection measures in the early stage of accident handling are relatively lacking, so the degree of danger in the early stage work is still high. At the same time, it is limited by the size of the roof fall and the roof of the cavitation area, which further increases the difficulty of the operation. Contents of the invention [0003] Aiming at the problems existing in the prior art, the present invention provides a roadway roof fall treatment device and method, which can provide effective protection means for the staff in the early stage of the treatment operation of the empty area, so that the staff ca...
