Coal mining machinery is a specialized machine used for coal mining, represented by the "three machines and one frame" system, which includes tunneling machines, coal mining machines, and hydraulic supports for scraper conveyors. Nowadays, "unmanned underground is safe" has become a safety consensus in the coal mining industry, so unmanned intelligent coal mining collection systems have become mainstream. The intelligent hydraulic servo system is the most critical part, and magnetostrictive displacement sensors, pressure transmitters, and height sensors are all core components.
