During the mining operation, according to the different cutting purposes, the cut surface is divided into two types: the separation body cutting surface and the disintegrating shaping cutting surface. According to different cutting positions, the cut surface is divided into the vertical surface, horizontal surface and inclined surface for cutting. Different types of cutting surfaces, the beaded rope threading method is slightly different. The threading of the beaded rope around the vertical cutting surface of the separator is the most basic method of threading the beaded rope. It is usually divided into the threading of the hole to the hole between the confluence holes and the threading of the hole opposite the hole between the drilling and the cutting surface or the burning surface. When the beaded rope needs to pass through the vertical and horizontal through holes surrounding the vertical sawing surface, first pass the guide rope through the vertical hole and the horizontal hole, and then connect the guide rope to the beaded rope. Under the traction of the guide rope, Thread the beaded rope around the cut surface. Before threading, you need to prepare a steel bar with a pawl head and a crank handle. The diameter of the steel bar is 8-10mm, and the length is 50-100cm longer than the horizontal drilling hole. The eccentric distance of the crank handle is 15-20cm. The pawl part is preferably made of high-elasticity steel wire, which is welded and fixed with the steel bar or wound with thin lead wire, and the diameter of the head is 10mm smaller than the diameter of the horizontal hole. In addition, a cotton thread with a diameter of 1-1.5mm or a nylon thread with good flexibility needs to be prepared as a guide rope, and its length should be at least 2-3m longer than the sum of the length of the vertical hole and the horizontal hole. And a number of galvanized fine lead wires with a diameter of 0.8-1.5mm, plastic electrical tape, wire cutters and other auxiliary materials and tools.
