针对南酮矿务局南酮煤矿深部开采复杂的采矿地质条件，运用求解非一性大变形问题有限差分法（FLAC），对南桐煤矿二井三区开采引起的岩体移动、矿山压力分布和地表沉陷进行了研究，总结出了南桐煤矿深部开采引起的岩体移动的基本特征，采场周围矿山压力分布规律和地表沉陷的相关参数，所得结果对现场开采、工作面支护和采空区处理具有一定的指导作用，对开采所致的地表沉陷的治理提供了科学的依据。

[Abstract]
According to the complex conditions of deep excavation in Nantong mine, FLAC program are carried out for strata movement, ground pressure and surface displacement due to coal extraction. Based on the analysis of Nantong mine, the basic features of strata movement, the fundamental behavior of ground pressure and the related parameters of surface displacement are obtained. The results are of referential value for mining, supporting and preventing of surface displacement.
