1.Downhole drilling machine: When drilling a downhole gun hole with a aperture less than 150 mm, in addition to the application of a rock drill, it can also be used to drill a small diameter of 80 ~ 150 mm. When drilling a gun hole with a diameter of less than 70 mm in coal or softer mineral rock, it is generally used to drill or air drill, driven by a motor (or air motor) to drill the drill pipe, and the rock (coal) chips drilled out are discharged through the spiral groove on the drill pipe.

Operational Precautions for the Integrated Drilling and Piling Machine:
Maintaining Your Sump Pump
Given Mars' low-pressure environment, the search for life has become increasingly complex. While the thin atmosphere presents challenges, it also raises intriguing possibilities. Life that could potentially exist on Mars might have adapted to these harsh conditions, thriving in subsurface environments where pressure is higher and water may remain stable in liquid form.
