Divided into pneumatic roof bolter, outrigger-type anchor drill rig.
And drilling rigs supporting the drilling tools, due to different ways to break the rock different, in general, there are rotary rock drilling tools, impact Coal Mine Drill Rig Rock Bolt Drill and rotary impact rock drilling tools.
At present, the most commonly used coal mine drilling rig for the speed of single pneumatic drilling rig and rotary hydraulic drilling rig.
MQT-130 Pneumatic 3 Stage Roof Bolter for the roof hardness f ≤ 10 coal, semi-coal road rock and rock roadway anchoring operations, set drilling, mixing, installation of a bolt and a. For coal mine underground support operations, but also for iron ore, tunnel construction and slope protection work.
