Introduction/Features

Hydraulic roof cutting water jet machine for mining, suitable for roof cutting and drilling below the mine, with drilling diameter of 55~75m; capable of radial cutting within the钻孔, with cutting diameter of 100~550mm (varies with rock strata), cutting speed of 10~20m/h; after cutting, water is injected into the钻孔 to achieve directional hydraulic fracturing; it serves the purpose of roof pressure relief, leaving a passage along the void, and roof caving. The equipment can also cut U-shaped steel, round chains, anchor cables, and more in the mine.
