【摘要】 对白云鄂博铁矿主采场1 626 m南D区4#滑体从出现裂缝到滑塌全过程进行监测,分析总结了其形成机理及演变规律,及时准确的预测了滑塌时间,有效的指导了该滑体周边及下部台阶的安全生产,避免了滑体塌落对设备及人员的伤害,同时提出了滑塌后有效的治理方案;对矿边坡管理工作具有重要的意义。更多还原

【Abstract】 The whole process from the occurrence of cracks to slumping of 4#slip mass in 1 626 m south D area of main stope of Bayan Obo Iron Mine was monitored. The formation mechanism and evolving regularity were analyzed and summarized so that the slumping time was predicted timely and accurately. As a result,the safe production around and at lower step was effectively guided,the damages of equipment and personnel when slip mass caving were avoided and the effective treatment scheme after slumping was put forward simultaneously,which were with significant meanings to the side slope management of the mine.更多还原
