Abstract

The invention belongs to the technical field of supporting, and particularly relates to a supporting method and application special for a rock burst roadway. The supporting method comprises a coal mine roadway, a supporting unit and an anchor cable net tensioning assembly, wherein the coal mine roadway comprises a roadway roof and a roadway side, a supporting area and a lap joint area are pre-arranged on the side face of the roadway side, a supporting anchor eye is formed in the supporting area, and a lap joint anchor eye is formed in the lap joint area; the supporting unit comprises an anchor cable net, a supporting anchor rod, a supporting gasket, a supporting nut, a lap joint anchor rod, a lap joint gasket and a lap joint nut; and the anchor cable net tensioning assembly comprises a bottom plate, a horizontal sliding groove, a horizontal sliding block, a connecting plate, a telescopic inner screw rod, an outer screw cylinder, a vertical plate, a driving screw rod, a rotating rod, a mounting rectangular groove, a vertical sliding groove, a servo motor, a vertical screw rod, a vertical sliding block, a lower lap joint rod, a through hole, an extension rod, an ejector block, an upper lap joint rod and a power box. For the long anchor cable net, a single person can realize laying, and the efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of support, and in particular relates to a support method and application for a roadway dedicated to rock burst. Background technique [0002] A coal mine is a reasonable space excavated by humans when excavating geological layers rich in coal, usually including roadways, shafts, and mining faces. Coal mine roadway is a variety of passages drilled between the surface and the ore body, which are used to transport ore, ventilation, drainage, pedestrians, and various necessary preparation passages for metallurgical equipment to extract ore. Rocks in the natural state can be divided into consolidated rocks, cemented rocks, granular rocks, fluid rocks, etc. according to the combination characteristics of their solid mineral particles. The so-called consolidated rock refers to a rock in which solid particles of rock-forming minerals are rigidly connected and can maintain a certain shape after being broken. In th...
