ZDY1250 fully hydraulic tunnel drilling rig for coal mines

钻孔深度：

200

开孔直径：

Φ85、Φ115

终孔直径：

Φ65、Φ75

Features: It is divided into two types of drill frames: column frame and seat frame. Different drill frames can be selected according to the height and use of the coal tunnel.
This type of drilling rig can push the mesh conduit into the hole while drilling, successfully solving the key problem of gas drainage in high-gas mines with unshaped or soft coal seams, so this type of drilling rig Drilling rigs are also called conduit drilling rigs or pipe jacking rigs.
This type of drilling rig uses high-pressure sealed drill pipe and bottom hole motor to greatly improve the drilling capacity (avoiding the strong torque force of the drilling rig twisting the drill pipe's own weight, so this type of drilling rig is also called bottom hole motor drilling rig< br/> > Item
