The reserved reinforced anchor rod can damage a coal cutter, and meanwhile, if sparks generated after the anchor rod is impacted with the coal cutter meet local accumulated gas, gas explosion accidents can be easily caused, so that serious potential safety hazards are brought to underground production;
2. If the anchor rod entering the coal flow system cannot be taken out in time, accidents can occur to the transportation machinery, and serious consequences of tearing the adhesive tape of the adhesive tape transportation machine can be caused. In the production process, the anchor rod of the coal flow system is usually taken out by stopping the scraper conveyor, so that the opening probability of working face equipment is reduced, and meanwhile, the anchor rod wound on the roller of the coal machine also needs to be taken out by taking manpower and time, and the production of the working face is seriously influenced by the mode of processing the anchor rod.
The general process when the head (tail) is in the wrong cutter to take the anchor rod in the fully mechanized mining face extraction process at present is that when the coal cutter is in wrong cutter, the coal body in the triangular area is arched loose and then the anchor rod is taken out, but the method is behind, so that the method is difficult to master, has major potential safety hazards, and causes safety accidents and electromechanical accident frequency.
