ZYJ-270/170 prop producition drilling rig in underground coal mining
ZYJ-270/170 prop producition drilling rig in underground coal mining
The drilling rig is mainly used in the underground laneway for the hole drilling of water probing, gas release, coal probing, dust prevention and blasting hole for roof caving.
The machine consists of 4 parts, the drilling part, the prob, the hudraulic power pack, and the operation panel.
The prop is a hydraulic cylinder, the height of the prop can be optional according to the laneway height.
The function of the prop is to stablize the drilling rig during drilling by press tightly against the roof and the floor of the tunnel. The second function of the prop is the drilling part can move up and down along the prop so that can make the drilling at the different height.
The drilling part can also attached to the roadheader to save the space.
