Abstract

According to the actual conditions of the deep inclined open-off cut for the No.1307 fully mechanized top coal caving mining face in Yangcheng Mine,with the winch strength of the hoisting system checked,the basic hydraulic powered supports of the coal mining face were determined to be assembled in the mining gateway and to be located and installed in the open-off cut.The transition hydraulic powered supports were be installed in the open-off cut.The related installation technique was applied and the related safety technical measures were setup.Thus the safety and rapid installation of hydraulic powered supports was realized in the deep inclined fully mechanized top coal caving mining face.
