At present, the release of the anchor cable support mainly depends on an anchor withdrawing tool or forced shearing, and when the anchor withdrawing tool is adopted, on one hand, due to the fact that time is long, environment in a roadway is poor, an anchor net is broken, an anchor cable lock is corroded, the anchor withdrawing tool is difficult to install, 2-3 persons are needed to cooperate together to complete the release, the number of persons is large, and the speed is low; on the other hand, when the anchor cable steel strand is released, the anchor cable steel strand has great elasticity, the phenomenon of bullet collapse occurs in the anchor releasing process, the safety of operators is threatened, and the safety factor is low. When the anchor withdrawing tool cannot be used, a forced shearing method is mainly adopted, the method mainly uses oxygen for cutting, and the hidden danger of gas explosion exists due to open fire work.
