Drilling machinery is divided into two types: rock drilling rigs and drilling rigs. Drilling rigs are divided into surface drilling rigs and downhole drilling rigs. A rock drill is used to drill blast holes with a diameter of 20-100 mm and a depth of less than 20 meters in rocks above medium-hardness. According to their power, they can be divided into wind, internal combustion, hydraulic and electric rock drills. Among them, pneumatic rock drills are the most widely used.
