摘要(Abstract)：

在遥感解译的基础上,实地调查了神木县煤矿开采区地面塌陷现状,阐述了地面塌陷分布、发育特征及发育规模。共发现大面积地面塌陷30处。地面塌陷规模以中型为主,稳定性以较差为主,险情等级以小型为主,均为高强度采煤造成。单个塌陷区最大面积27.67 km2,煤炭开采强度与塌陷发育程度关系密切。论述了石圪台村、榆神路煤矿、蛇疙瘩村、榆家梁煤矿、后柳塔村、沙沟茆村等典型村镇地面塌陷特征。地面塌陷导致的地质环境问题日益突出,截至2015年4月30日,已经导致了48次1.5~3.3级的塌陷地震,诱发区域性地下水水位下降、井泉干涸与河流断流、水域面积萎缩,并进而产生一系列生态环境问题。
The paper clarified the ground subsidence characteristic derived from coal mining and its environment problems in Shenmu County by remote sensing interpretation and field investigation. There are 30 palaces where larger area ground subsidence have been found. The paper explained its distribution, development and scale. The ground subsidence derived from high intensity coal mining were of medium size, worse stability and small danger level. The paper discussed the ground subsidence characteristic of typical town and coal mine, including Shigetai Village, Yushenlu coal mine, Shegeda village, Yujialiang coal mine, Houliuta Village, Shagoumao Village. The geological environment problems caused by ground subsidence had become increasingly prominent, up to April 30, 2015, it has led to 48 collapse earthquakes of amplitude 1.5 to 3.3, and induced regional groundwater drawdown, springs and wells dried up, rivers and ground water area were shrinking, and thus produced a series of ecological and environmental problems.
