DTH drilling can be performed in almost any rock drill-ability category. It is a common drilling equipment in the natural gas extraction, mineral extraction,drilling water wells, construction, creating oil wells. DTH drilling rigs can be equipped with diesel or electric motors according to different working conditions. During the rock drilling process, the impactor sneaks into the borehole, which can reduce the energy loss caused by the impact of the drill rod, thereby reducing the influence of the drilling depth on the borehole.
