ZDY800 type hydraulic tunnel drilling rig is mainly used for coal mine gas drainage drilling boreholes (row),anti fire hole grouting,the coal seam water injection hole, the outburst pressure relief hole, exploration water, geological exploration hole and other engineering drilling. It can be used for rock solid coefficient f ≤ 7 kinds of coal, rock drill. Configure the appropriate drill bit, drill pipe, drill can also be coring, drilling in soft coal project.

features
