Taking the liquid used in the hydraulic support system of intelligent fully mechanized caving face of Pingcoal mine as the research object,x-ray fluorescence spectrometry and gas chromatography-mass spectrometry were used to analyze the pollutants in the emulsion tank and backwashing filter element.the results show that the blockage problem of the pilot filter is mainly caused by organic adhesive pollutants composed of erucic acid amide and 2,2'-methylene bis-(4-methyl-6-tert-butyl phenol),that is,by mixing grease into the hydraulic system and aging rubber material.The results provide an important basis for formulating effective pollution control and system maintenance strategies.
