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.

1. Rotary Drills These are commonly used for deep hole drilling, making them ideal for mineral exploration. Rotary drills operate using a rotating drill bit that cuts through rock layers with the aid of a drilling fluid that cools the bit and removes cuttings from the hole.
2. Percussive Drills These drills utilize a hammering action to break rock apart, making them effective for hard materials. They are often used for both surface and underground mining operations.
