The DTH drilling rig (down-the-hole drilling machine) is a kind of drilling machine, which is mainly used for drilling in rock formations. The down-the-hole drilling rig uses the impactor and the DTH drill bits submerged into the bottom of the hole to impact and crush the rock. Therefore, it is called down-the-hole drilling machine equipment. YG DTH drill rig machine is widely used in metal mines, hydropower, transportation, building materials, harbors, and national defense projects.
Down the hole drill rig can drill holes in rocks above medium hard (f8). Therefore, down-the-hole drilling machine equipment is suitable for large-diameter blast hole drilling in small and medium-sized mines. Road construction, water conservancy, and rock engineering. And drilling anchor holes in slope support, tunnel support, and foundation pit support. The main drilling object of the DTH drilling machine is the rock stratum.

The working principle of the mining drilling rig is the same as other rock drilling rigs. Which includes the drilling process of impact, rotation, ballast removal, and advancement. DTH machine belongs to percussion rotary drilling. The difference is that the impactor of the down-the-hole drilling machine is installed at the front end of the drill rig rod, submerged into the bottom of the hole. And continues to advance as the drilling extends.
