摘　　要：通过对北皂煤矿四采区4402综放面上下巷变形全程详细观测,得出了在工作面不同推进阶段巷道的变形规律,分析了巷道变形的力学机理,提出了巷道支护的技术对策。According to the whole detailed observation of roadway distortion of 4402 full-mechanized caving mining face in the 4th mining area of Beizhao Colliery, roadway distortion rules of different advancing phases of mining face were obtained in this paper. Mechanics mechanism of roadway distortion was analyzed and technology countermeasures were put forward for roadway supporting.
