small volume, light weight, easy to operate and maintain, gear compressed air motor, operation stable and high reliability
The pneumatic roof bolter drill is widely used as coal roof bolter operation for the rock hardness less than f8 gateway of the coal bed, or half gateway of the coal bed. It can be used not only for drilling bolt hole, but also for the anchor cable, and also the rolling roof bolter for agitating and installing polyester drug. As for the anchor cable, no need other tools, screwing of bolt and nut can be realized by one time and come to the requirement of initial bolting and pre-tightening force.
This model can drill coal bed gas and detection hole of water by changing drill sleeve, the detection depth can be max 20m and the diameter of the hole is 75mm.
