摘 要:某铁矿经过长期开采后形成大量采空区,为了避免空区塌落造成严重后果,对该铁矿采空区进行详细探测,将其455中段空区进行数量统计和安全等级划分。制定了"充填法处理空区,隔离封闭法作为辅助方式"的空区治理方案。运用数值模拟方法验证了治理方案的有效性。经过充填治理的采空区,其稳定性达到了预期效果,可消除采空区的隐患,并能够保证矿山后续开采安全进行。A large number of goafs were formed after longterm mining in an iron mine. In order to avoid the serious consequences of collapse, the goafs of this mine were detected in detail. And the quantity statistics and security classification were conducted for the goafs in 455 level. The treatment plan was determined, which used filling method to manage goafs and the isolation method as an auxiliary means. Then its effectiveness was validated by numerical simulation. After filling control, the stability of goafs achieved expected result, which can remove the hidden danger of goafs and ensure the safety of following mining.
