| 摘 要： | 急斜特厚煤层开采扰动区(Mining Disturbed Zone,MDZ)煤岩应力与变形规律复杂,采动影响下局部煤岩层滑移造成应力集中,使煤岩体产生"强烈"的动力学失稳与破坏.以大洪沟煤矿B3+6急斜特厚煤层综放开采为工程背景,通过现场声发射(acoustic emission,AE)监测,分析采动条件下煤岩介质动力学失稳及破坏规律,为制定解危对策提供科学依据.

| Abstract: | The movement regularity of heavy and steep coal seam disturbed mining zone is complex.Because of the formation of mining strata partial slip gravity stress,the influence caused by coal and rock stress concentration produces strong dynamic destabilization and destruction.Taking B3 +6 heavy and steep coal seam fully-mechanized sublevel caving mining in DAHONG coal mine as engineering background,the dynamic destabilization and destruction regularities of coal and rock are analyzed by acoustic emission monitori... |
