[0002] Coal mining refers to the process of extracting coal resources from underground or open-pit deposits. With the continuous growth of global energy demand, coal, as an important fossil fuel, occupies an important position in the energy structure. Coal mining technology has evolved from traditional manual mining to modern mechanization, automation and intelligence. The softening liquid winch is a heavy equipment used for lifting and transportation in coal mines. It is mainly used for pulling and lifting heavy objects, such as hydraulic supports and coal mining machines. Its working principle is to use emulsion as the power medium and drive the winch through the hydraulic system to work.
