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

1, the power head hydraulic combined type drill. The volume of wood structure, convenient installation, shift, underground transport.

2, the unique hydraulic system, double pump, hydraulic chuck, hydraulic clamp is safe, convenient, unloading drill pipe, saving.

3, by the hydraulic pump, drilling rig power head, frame, operation table, the columns support the component parts, work with high pressure tubing connection, away from the wellhead operation, safety.

4, the design of hydraulic system is mature, simple, reliable, easy to master, easy to solve the fault analysis.

5, double column or four column support, an anchor drill porous, light weight, high efficiency, strong applicability.
