Abstract: Taking ZY9000-25/50D two-column supporting shield hydraulic support at 15101 working face of a coal mine as analysis object, control effect of setting load and the working resistance of hydraulic support on working face roof of, and operation characteristics of support was analyzed through the measured pressure data and three-dimensional graph. The results show that the average setting load of ZY9000-25/50D type two-column support hydraulic shield support is 3 168.015 kN in the mining process of working face, which only accounted for 44% of the rated setting force; the average working resistance is 4 850.615 kN, it only accounted for 53.9% of the rated resistance. Through the analysis of the adaptability of the support, the article puts forward a new parameter for the rated setting load and rated resistance work of hydraulic support and verifies the theory, determines that the ZY6800/17/36 type two-column support hydraulic shield supports is adapt to the 15101 working face.
