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.
4. Minimal Vibration and Noise Unlike traditional drilling methods that may cause significant surface vibration and noise, DTH drilling produces cleaner operations. This characteristic is crucial in urban areas and sensitive environments, leading to fewer disturbances.

2. Cost-Effective Operation Diesel-powered compressors like the CFM 185 tend to have lower operational costs over time compared to their gas counterparts, particularly in heavy-use scenarios.
The reason:The suction pipe is not filled with water
Blocked suction line or inadequate valve opening
The inlet pipe of the pump, the meter or the stuffing box are serious
