摘要
基于现有冲击地压监测技术与装备,结合综掘工作面实际情况,研究了深部沿空综掘工作面冲击地压监测方案。对深部综掘工作面煤体钻孔应力、巷道收敛变形、锚杆受力、煤粉量情况、微震情况进行监测方案设计,得出适用性较好的深部沿空综掘工作面冲击地压监测方案,为下一步同类巷道掘进期间冲击地压提供监测依据。
Based on the existing rock burst monitoring technology and equipment, combined with the actual situation of fully mechanized excavation face, studied the rock burst monitoring scheme of fully mechanized working face along gob in deep, designed the coal drilling stress, roadway deformation, the force of bolt, the amount of pulverized coal, microseismic monitor scheme obtained the good rockburst monitoring scheme suiting fully mechanized excavation face along gob, and provide the monitoring basis for rock burst during the next similar tunneling.
