摘要: 针对大中铁矿Ⅱ#矿体开采后存在的空区危害,提出了采取控制冒落与诱导冒落相结合的采空区处理方案,按空区冒落气浪冲击原理建立了模型,并对冲击危害进行了评价,建议设置空区垫层厚度、地表陷落区的圈定及警示标记,有效地解决了大中铁矿的空区危害。
关键词: 空区, 冒落, 垫层
Abstract: For the goaf hazards existed after Dazhong iron ore Ⅱ# ore exploitation, goaf treatment plan of caving control combined with induced caving was proposed.Shock model was set up according to goaf caving blast shock principles and caving blast shock hazards were evaluated.Suggests were proposed for cushion thickness, delineation of surface caved area and setting of warning marker of goaf, solved the hazard of Dazhong iron ore goaf effectively.
Key words: Goaf, Caving, Cushion
