The mountain rig is mainly used for exploration drilling of complex surface such as mountain, loess, hill, Gobi and farmland. The rig is fully hydraulically driven, and the mountain area mainly uses air drilling and air shock drilling. In other areas, the replacement of the drill can achieve spiral drilling, and the addition of a mud pump can achieve mud drilling.
