Mining machinery is the mechanical equipment used for directly mining useful minerals and mining preparation, including: mining machinery for mining metal ores and non-metallic ores; Coal mining machinery for coal mining; Oil drilling and production machinery for oil exploitation. The yi pneumatic disc shearer was designed by British engineer Walker and was successfully manufactured in about 1868. In the 1880s, hundreds of oil wells in the United States were successfully drilled with steam powered percussion drills. In 1907, a rotary drill was used to drill oil wells and natural gas wells, and since 1937, it has been used for open pit drilling. With the progress of technology, a new type of hydraulic fracturing technology is gradually facing the market. Hydraulic fracturing is also called water fracturing. The technology of water fracturing rock and concrete is a new technology of non blasting broken rock mass, rock block and concrete structure (component). It is a kind of engineering equipment that uses the huge expansion force generated by the work of pressure energy to separate the rock block from the rock mass or reduce the fragmentation by filling the tubular sealed elastic expander inserted into the borehole with high-pressure water.
