Build a brand with integrity and win the market. Welcome to call us! Coal tunnel bolt support has outstanding advantages in improving support effects, reducing support costs, accelerating tunnel construction, reducing auxiliary transportation volume, reducing labor intensity, and increasing tunnel section utilization. Therefore, it has received widespread attention from major coal-producing countries in the world. And competing to adopt the important development direction that represents the national coal roadway support technology.
It has the advantages of safety, explosion-proof torque, large speed, high volume, small size, light weight, simple structure, easy disassembly and assembly, etc. After being disassembled, each component weighs less than one kilogram. Among them, / is the pneumatic column drilling rig with the highest torque of its kind in China. The rotation of the machine host has forward and reverse functions, making it easy to drill and push out drilling tools. The feed adopts an independent motor with high feed force and low failure rate. The rotation speed and feed speed can be adjusted by controlling the air intake volume. This series of drilling rigs can be used with high-efficiency spiral drill pipes and geological drill pipes and are widely used in drilling construction of coal mine water exploration, water injection, gas drainage, pressure holes, tunnels, anchor holes, etc.
