| 摘 要： | 利用RFPA模拟软件分析房间矿柱在大范围岩层移动和应力集中控制作用的基础上，提出了应用隔离矿柱控制采空区连锁式破坏的设想，并进行了数值模拟；在此基础上以较低强度条带充填体代替隔离矿柱，同样有较好的效果。

| Abstract: | Based on analysis of the control effect about displacement of large scale stratum and stress centralize of the pillar with RFPA.,assume that the mined-out area hazard could be controlled with isolate pillar restraint the circular damage of the collapse was,according to the RFPA simulating,the effect is clear evidence,then the importance that filling body with broader and lower strength substituted for isolate pillar in mined-out area hazard controlling was discussed. |
