Application

Mainly used to detect geological structure coal seams, explore and discharge water and gas, coal seam water infusion, discharge pressure ports, drilling of bolt holes in tunnels, stirring of bolt and nuts installation; it can also be used for stirring of rock tunnel resin bolt.

Features

● Using column to overcome heavy weight of drilling machine and avoid reverse torque happened during operation.

● Specially designed for underground with high gas concentration and the tunnel where is difficult to get electric power supply.

● Portable design, explosion-proof, high torque, high speed, small size, high efficiency, simple structure and easy to maintain.

● A good drilling solution for mining industry. High efficiency, good quality, low labor strength, and less footage fee.
