The MQT series pneumatic roof bolter is primarily designed for drilling and installing anchor bolts in underground coal mines, tunnels, and mining support projects. It assists in reinforcing roofs and sidewalls to ensure operational safety.
Each model of our pneumatic roof bolter can be equipped with two standard types of connection interfaces for the drilling rods: B19 and B22. This versatility allows you to adapt to existing drilling equipment.
The applicable working air pressure is between 0.4 and 0.63 MPa, with a rated air pressure of 0.5 MPa. The flushing water pressure should range between 0.6 and 1.2 MPa to ensure efficient flushing and dust suppression.
The drilling rig is equipped with a specialized silencer system designed to optimize ventilation noise. It successfully keeps the operating noise levels at or below 90 dB(A), significantly improving the comfort of the workspace.
Yes. Beyond the standard rig specifications, we supply a variety of custom drill bits and rod fittings designed to match different geological formations and rock hardness ratings for maximum penetration rates.
