| 摘 要： | 条带开采是进行建筑物下采煤时限制地表变形的措施之一,深部开采地表移动和变形规律与一般地质采矿条件下的地表移动规律相比发生了较大改变.以极不充分务带开采地表沉陷理论为基础,以林南仓矿实测资料为依据,对开采区域-650水平深部条带开采进行了预计,预计下沉的最大偏差为68mm,预计下沉中误差为39mm,远远小于经验公式预计下沉的最大偏差319mm和预计下沉中误差217mm.表明基于极不充分开采的地表沉陷预计理论改善了预计精度,对于研究深部条带开采地表移动和变形的规律,解放建筑物下压煤,实现煤炭资源的可持续发展具有重要意义.

| Abstract: | Strip mining is one of the measures controlling surface deformation when mining under structures.The rule of surface movement and deformation for deep mining is much different from the one of mining under ordinary geological conditions.Based on surface subsidence theory of super-subcritical extraction and field observations in Linnancang mine,subsidence induced by strip mining at-650 m level was predicted.The maximum deviation of predicted subsidence is 68 mm with a mean square error is 39 mm.Those magnitud... |
