Applications of Drilling Equipment

1. In the mineral deposit exploration, especially the non-ferrous and rare metal exploration, the tunnel drilling rigs are used for ore deposits searching, exploration and reconnaissance of geologic structure ore body as well as sampling and verification.

2. The engineering drilling rigs are applied to geotechnical foundation constructions, including building base, plant foundation, high-speed rail base and road infrastructure.

3. The drilling equipment is generally used to drill observation wells, vent holes, drain holes, gas drainage hole, grouting hole, blasting holes, anchor holes and the pilot hole.

4. In other areas of geotechnical engineering, the tunnel drilling rig and technology can be used for slope strengthening of dam foundation, governance of geological disasters, deep excavation pit supporting, as well as underground constructions at the aspects of industrial, commercial, transport and military.
