通过对阳城县煤矿区中小煤矿土地塌陷数量、类型、程度以及塌陷破坏特征的调查，分析了造成土地塌陷的原因，探讨了黄土丘陵区中小煤矿在采煤过程中造成土地塌陷与上覆岩性、地层构造、地形地貌、煤层开采条件、采煤与顶板管理方法的关系，以及土地塌陷规律，为今后综合治理土地塌陷提供依据。 By investigating the quantity, type and degree of land subsidence, as well as the characteristics of collapse and collapse in small and medium-sized coal mines in Yangcheng County, the causes of land subsidence are analyzed. The reasons of land subsidence and overlying rock during the coal mining process in middle and small coal mines in loess hilly region are discussed Sex, stratigraphic structure, topography, coal seam mining conditions, the relationship between coal mining and roof management methods, as well as the law of land subsidence, and provide the basis for comprehensive control of land subsidence in the future.
