Drilling machines are divided into rock drills and drilling rigs. Drilling rigs can also be divided into open-air drilling rigs and underground drilling rigs. ① Rock drill: It is used to drill holes with a diameter of 20~100mm and a depth of less than 20m in medium hard rocks. According to its power, it can be divided into pneumatic, internal combustion, hydraulic and electric rock drills, among which pneumatic rock drills are widely used. ② Open pit drilling rig: according to different working mechanisms for crushing ore and rock, it can be divided into wire rope percussion drilling rig, down-hole drilling rig, rotary drilling rig and rotary drilling rig. The wire rope percussion drill has been gradually replaced by other drills due to its low efficiency. ③ Underground drilling machine: when drilling the underground blast hole with the hole diameter less than 150 mm, a small diameter down the hole drill of 80~150 mm can be used in addition to the rock drill.
