Abstract: With the analysis on the application conditions of the overseas high cutting fully mechanized coal mining equipment imported by Xiegou Mine, it was fou nd that the stability of the surrounding rock at the coal mining face end would have high influences to the advancing speed and the equipment operation rate of the coal mining face as well as to the spalling of the coal mining wall. Therefore the support of the face ends and gateways should be enhanced, the mine strata pressure of the coal mining face should be timely and dynamically monitored and measured and the timely moving forward of the powered support with certain roof pressure could impr ove the advancing speed of the coal mining face.In regions with joint crack development of the coal wall, loose and broken coal seam and serious spaling, the enhance d support or coal wall consolidation method, serious controlled face quality management and other safety measures should be conducted.The results showed a max dai ly production of No.18102 coal mining face was reached at 42 180 t, the month circulated rate was reached at 85%, the average mining efficient rate of the coal mining face was 902 t/person, the coal mining rate was over 93%.
