摘要
地面塌陷是辽宁地质灾害的显著特征。可分为采矿塌陷、岩溶塌陷、地震塌陷三种类型。尤为突出的是煤都抚顺、本溪、阜新、北票等地都有严重的采矿塌陷发生。岩溶塌陷在我省沈大经济交通干线鞍山、辽阳、本溪、海城、瓦房店、金州、大连均有发生。地面塌陷灾害对市区的工矿企业、公共设施、道路交通、居民住宅、农业耕地已构成了严重的威胁，给城市建设和人民生命财产、工农业生产造成巨大的经济损失。本文对地面塌陷的类型、危害与成因以及影响的因素进行了探讨。
Land collapse in Liaoning province is the types of the mining collapse,the subterranean karst collapse and the seismic collapse The shape of the mined out collapse consists of a series of hollow and fractures The depths of which are several meters to 30 meters or even more It is dangerous to highway traffic,residential building,cultivated land,and also did serious damages to the urban construction,the public life and properties as well as industry and agriculture The mined out collapse should be investigated in detail and controlled accordingly The measures of scientifically limiting the quantity of exploiting groundwater and the measures of monitoring the groundwater to reduce the collapse to the minimum extent
