| 摘 要： | 针对资源枯竭矿区已经进行了多年开采而在地下浅部已留下很多老采区和地层已遭受数次沉陷破坏的特点，提出了深井开采及深浅部同时开采(重复采动)导致地层进一步破坏的特征和地层自下而上的沉陷规律及其损害累积效应，并借助北票矿区已经进行127a开采的实例，综合分析了资源枯竭矿区深井开采引起地层再破坏的复杂性及资源枯竭城市再生地层结构抗震性能的下降机理、评价方法和恢复措施。

| Abstract: | In the resource depletion area,there are many abandoned stopes and the strata have been destroyed many times after years of mining in top strata. The rules of further destruction caused by deep mining or simultaneous mining at the top and deep strata,and subsidence along depth direction and the accumulative effect of damage are analyzed. The complexity of strata redestruction and the mechanism of worsening of earthquake- resistant behavior in the resource depletion area are discussed,and evaluation methods and resuming measures of earthquake-resistant behavior are proposed. |
