Coal mining machinery such as shearer is one of the most important comprehensive mining equipment in coal mine. Once it breaks down, the consequences cannot be estimated. The data shows that about 2 / 3 of the faults in the hydraulic system of coal mine machinery are caused by the pollution of hydraulic oil. Therefore, this paper first analyzes the types and properties of various pollutants, then describes the harm of pollutants to the hydraulic system, and finally puts forward a comprehensive control scheme of hydraulic oil pollution, which provides a reference for engineering practice.
