摘　　要：晋城市区周围由于数十年来的地下采矿,形成了大量的采空区。通过遥感地质解译、调查,利用多时相卫片、航片、数字高程模型等技术资料的研究,对晋城市周围的采空区有了较全面掌握。确定了采空区塌陷28处,地裂缝23处。根据采空区年限、顶板岩性、开采层数、地面塌陷幅度等多种因子,将采空区划分为极不稳定、不稳定、较不稳定3种类型,确定了极不稳定区5个,不稳定区4个,较不稳定区13个。Decades of underground mining around Jincheng city results in a large quantity of goal. By virtue of remote sensing geology interpretation as well as investigation, and research on technical materials of multi-temporal satellite images, aerophotos, digital elevation models, the paper gives a fairly comprehensive grasp of goal around Jincheng city. 28 sinks and 23 crevices are determined in the goal. According to various factors, such as goaf＇s age, roof lithology, the number of the exploited layers, and the status of ground sinks, the goaf is divided into three types： extremely instable area, instable area, and comparatively instable area. 5 extremely instable areas, 4 instable areas and 13 comparatively instable areas are determined.
