During mining operations, 3-4 cooling water adding points are generally set according to the position of the cutting surface and the position of the saw joint of the cutting surface.
The main cooling water entry point is at the entrance of the diamond wire saw into the ore body, and the cooling water at the point must be sufficient; In the horizontal hole intersection of the vertical hole mouth, need to place a water point; Two auxiliary water filling points must also be placed at the exit and corner of the diamond wire saw around the horizontal plane. With the movement of the section plane, the two auxiliary water filling points located at the corner of the horizontal plane should move with the change of the cutting position of the diamond wire saw. After the cutting surface moves, in order to ensure that the cooling water entering the vertical hole will not lose, yellow mud can be used to plug the saw joint formed by the horizontal section, so that the water flow can only flow out along the cutting position of the diamond wire saw and the ore body, so as to improve the cooling effect.
