通过对神木县大柳塔地区开展 1∶ 5万生态地质填图 ,首次在大柳塔镇附近发现地面沉陷裂缝群 ,其分布范围与煤层采空区吻合 ,延伸方向和采煤巷道一致 ,未来采空区的范围将是可能发生地裂缝的地段 ,应引起重视。
By carrying out 1: 50000 eco-geological mapping of Daliuta area in Shenmu County, it is the first time that a subsidence group of ground subsidence has been found in the vicinity of Daliuta town. Its distribution range is consistent with that of coal seam. The extension direction is consistent with that of coal mining roadway. The scope of the area will be a place where ground fissures may occur and deserves attention.
