摘　　要：分析了近距离煤柱作用下工作面开采时矿压显现特征及显现机理,通过制定合理有效的技术措施,采用超前支护、加套木梁、调整回采方向、加强矿压检测、实行浅孔注水等方式,确保了工作面安全开采。It is analyzed that the characteristics and apparent mechanisms of mine pressure under action of close distance coal pillars when the face is close-pillar mining.The reasonable and effective technological measures are worked out,such as advance support,jiacketed timber beams,adjust the direction of recovery,strengthen the rock pressure testing,the implementation of shallow hole injection etc,and these measures will ensure the safety of mining face.
