① Rock drill: used to drill holes with a diameter of 20-100 millimeters and a depth of less than 20 meters in rocks of medium to hard or above. According to their different power, they can be divided into pneumatic, internal combustion, hydraulic, and electric rock drills, with pneumatic rock drills being the most widely used. ② Open pit drilling rig: According to the different working mechanisms for crushing ore and rock, it is divided into steel rope impact drilling rig, down-hole drilling rig, rotary drilling rig, and rotary drilling rig. Steel rope impact drills have gradually been replaced by other drills due to their low efficiency. ③ Underground drilling rig: When drilling underground blast holes with a diameter less than 150mm, in addition to using a rock drill, small diameter down-the-hole drills with a diameter of 80-150mm can also be used.

Coal mining operations have evolved from semi mechanization in the 1950s to comprehensive mechanization in the 1980s. The comprehensive mechanization of coal mining is widely used, including shallow and deep double (single) drum combined shearers (or planers), flexible scraper conveyors, and hydraulic self moving supports, to achieve comprehensive mechanization in the crushing, coal loading, transportation, support and other aspects of the mining face. The double drum shearer is a coal falling machine. The electric motor passes through the cutting part of the reducer to transmit power to the spiral drum for coal falling, and the movement of the machine is achieved by the electric motor passing through the traction part of the transmission device. There are basically two types of traction methods, namely anchor chain traction and non anchor chain traction. Anchor chain traction is achieved by meshing the sprocket of the traction part with the anchor chain fixed on the conveyor.

Land oil drilling and production machinery. According to the mining process, it is divided into drilling machinery, oil production machinery, well repair machinery, and fracturing and acidizing machinery that maintain high oil well production. Drilling machinery is a complete set of mechanical equipment used for drilling or drilling production wells for the development of oil or natural gas. Petroleum drilling machines, including derricks, winches, power machines, mud circulation systems, pulley systems, turntables, wellhead devices, and electrical control systems. The mast is used to install crown blocks, traveling blocks, and hooks, lift other heavy objects up and down the drilling platform, and suspend drilling tools in the well for drilling.

Mining is the process of selecting useful minerals from the collected mineral raw materials based on the differences in physical, physicochemical, and chemical properties of various minerals. The implementation of this process is called mineral processing machinery. The beneficiation machinery is divided into crushing, grinding, screening, sorting (sorting), and dewatering machinery according to the beneficiation process. The commonly used crushing machinery includes jaw crushers, rotary crushers, cone crushers, roller crushers, and impact crushers. The most widely used type of grinding machinery is cylindrical mills, including rod mills, ball mills, gravel mills, and ultra-fine laminated self grinding machines. Inertia vibrating screens and resonance screens are commonly used in screening machinery. Hydraulic classifier and mechanical classifier are widely used classification machinery in wet classification operations. The commonly used flotation machinery for sorting is the full section air lift micro bubble flotation machine, while the well-known dewatering machinery is the multi frequency dewatering screen tailings dry discharge system. The most famous crushing and grinding system is the ultra-fine laminated self grinding machine.
