Abstract Hydraulic transmission medium was widely used in modern coal mining equipments, and synthetic esters were an excellent medium. The properties of different kinds of synthetic ester oil were introduced, and the differences between synthetic ester oil and mineral hydraulic oil were compared. The use effect was analyzed by the application examples of synthetic ester oil in coal mining equipments. The results showed that synthetic ester oil would have a wide application prospect in coal mining industry.
