Answer: Φ34mm-Φ50mm small diameter geological drill pipes can be used together with pneumatic column drilling rigs (ZQJC160 to 1000) with torque below 1000N/m/full hydraulic tunnel drilling rigs for coal mines (ZDY400, 540, 650, 1200). Large diameter geological drill pipes above Φ63.5mm are generally used together with full hydraulic drilling rigs (ZDY1900, 3200, 4000,) and crawler full hydraulic tunnel drilling rigs (ZDY6000), in addition, the matching of drill pipe and drilling rig should also take into account the drilling diameter and depth of the drilling rig, and the drilling diameter is inversely proportional to the depth.

The drilling diameter is inversely proportional to the depth as the configuration principle. The regular drilling depth of geological drill pipe produced by our company is about 300m m.
