This drilling rig is mainly used for drilling gas drainage holes, grouting fire extinguishing holes, coal seam water injection holes, outburst prevention and pressure relief holes, geological exploration holes and other engineering holes in coal mines. It can also be used for drilling geological exploration holes on the ground. Applicable to various coal seams and rock formations with rock formation solidity coefficients. When used underground, the cross section of the tunnel or drilling field is required to be larger than square meters, and the width is larger than the height and the structural characteristics
This drilling rig (as shown below) is a mechanical hydraulic transmission. Its mechanical transmission enables the drilling tool to obtain rotational motion and torque, and its hydraulic transmission enables The drilling tool obtains linear reciprocating motion and push and pull forces to complete the purpose of drilling holes in the coal and rock formations. The drilling rig is mainly composed of power head, gearbox, winch, brake, chassis, operating platform and drilling tools.
