The biggest advantage of the down-the-hole drilling rig is that in the process of rock drilling, the impactor dives into the hole to reduce the energy loss caused by the impact energy transmitted by the drill pipe, thereby reducing the impact of the hole depth on the rock drilling efficiency.

Single diesel engine for both the screw air compressor and the hydraulic system, compared with separated drill rig, the total power output of the diesel engine reduced by about 35%, and the maintenance cost lowered by 50%.

The down-the-hole drilling rig is equipped with an air compressor, which greatly improves the work efficiency.
