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.

The DTH hammer operates through compressed air, which is pumped through a series of valves and chambers within the hammer. When the air pressure builds up, it drives a piston that strikes the drill bit, creating a powerful force that breaks the material. This process continues in rapid succession, allowing the drill bit to penetrate the ground efficiently. The design of the DTH hammer allows for a larger drop height of the piston than traditional rotary drills, resulting in higher impact energy and better drilling performance.

One of the key drivers of this growth is technological advancement. The emergence of automated and remotely operated drilling rigs has revolutionized the industry. These advanced machines are not only more efficient but also enhance safety by minimizing human exposure to hazardous working conditions. Furthermore, innovations such as real-time data analysis and predictive maintenance have improved operational efficiency, allowing businesses to optimize their drilling operations and reduce downtime.
