Mining Machinery

Mining machinery is the mechanical equipment used for direct mining of useful minerals and mining preparation work, including: mining machinery for metallic and non-metallic ores; Coal mining machinery used for coal mining; Petroleum drilling and production machinery used for oil extraction. The first pneumatic disc shearer was designed by British engineer Walker and was successfully manufactured around 1868. In the 1880s, hundreds of oil wells in the United States were successfully drilled using steam powered impact drills. In 1907, a rotary drilling rig was used to drill oil and natural gas wells, and from 1937 onwards, it was used for open-pit mine drilling. With the advancement of technology, new types of hydraulic fracturing technology are gradually being introduced to the market. Hydraulic fracturing, also known as hydraulic fracturing, is a new technology for non explosive fragmentation of rock masses, rock blocks, and concrete structures. It is an engineering equipment that uses high-pressure water to fill a tubular sealed elastic expander inserted into a borehole, and utilizes the enormous expansion force generated by pressure energy to separate or fracture rock blocks from the rock mass.
