Abstract
In order to ensure roof safety during the connecting period of short and long faces at "hilt-shape " working face with 7 meters mining height,through the actual measurement of strata behavior laws at 52304 "hilt-shape" fully mechanized working face in initial stage,influenced by the shorter face of 52304-1 mining area,the lower key layer of overlying rock,the larger fracture length,the larger coefficient of direct roof,it presents the mine pressure laws of longer initial pressure step,lower pressure strength at "hilt-shape" working face with 7 meters mining height in initial mining stage,which is in favor of roof control in the connecting area of changing the "hilt" face form from short to long.关键词
