With the popularization of ten million tons of fully mechanized mining face, the quality, efficiency and intelligence of the integrated liquid supply system for fully mechanized mining cannot meet the requirements of the rapid development of safe, high-yield and efficient mines. This paper has developed a set of intelligent integrated liquid supply system for super high mining face. The flow of a single emulsion pump station reaches 800 L/min, and the rated working pressure reaches 40 MPa. The key technologies such as the overall design of the system, the large flow emulsion pump, the large flow spray pump, the ultra-high pressure pump, the electromagnetic unloading and intelligent frequency conversion control, and the automatic proportioning of emulsion are emphatically introduced. It has been successfully applied in Daliuta Coal Mine. The liquid supply efficiency of the pump station has been increased by 15%, and the moving speed has been increased by 20%. It can meet the needs of constant pressure liquid supply and high efficiency liquid use in the working face, and has realized the demonstration application of intelligent integrated liquid supply system in the super high fully mechanized working face.
