3. Open-air drilling rig: according to the different working mechanism of crushing ore and rock, it is divided into steel rope percussion drill, drilling rig, cone drill and rotary drill. Because of low efficiency, the steel rope percussion drill has been gradually replaced by other drilling RIGS. The drill pipe drives the pneumatic impactor and the drill bit to rotate together, and the piston of the pneumatic impactor is used to impact the drill bit to break the ore and rock, which is usually used in small and medium-sized mines to drill holes with a diameter of 80 to 250 mm.
1. Depth and Efficiency One of the most significant advantages of DTH rigs is their ability to drill to greater depths compared to conventional rotary drilling methods. They are capable of drilling depths exceeding 100 meters with great precision, which is essential in mining operations for reaching ore deposits.

The submersible drilling rig, available in both internal combustion and electric models, is a device for drilling holes in rocks. The characteristics of drill drilling is outstanding, according to different characteristics can be divided into many varieties, different varieties of drill drilling scope is not the same, facing the classification of drill drilling, the way is briefly introduced as follows:
The reason:
Inlet valve is not open or has silted
Suction line resistance is too high or blocked
Suction height is too high
