Widely used in hydraulic drilling coal seam and soft rock under various conditions, to solve the coal drill volatile explosive, is responsible for operation and maintenance and other issues, and as a mining face beams nest, dig hamstring purposes, is coal mining work ideal work surface drilling, the main features of the rig are: 1 The rig itself is without power, a safe, efficient, and other characteristics, especially suitable for high gas and coal dust explosion in danger of mine use; 2 drilling speed, The average coal drill faster than 1/3 of the time; three torque than twice the coal drill can improve work efficiency; 4 with emulsion as a power source; 5, compared with coal drill need to install power lines, electrical equipment water pipeline and dust; 6 small size, light weight, simple structure, easy operation and maintenance, can greatly reduce the labor intensity work. Mainly used to play ahead of the mining face hole machine, Caving Face hole, anti-fire hole, exploring water hole, gas exploration holes, taps, etc., such work is very advanced handheld rig, can replace the traditional coal and rock drill drill. Support to the coal face with emulsion hydraulic pump for the power source, using mechanized mining work surface particularly convenient.
