摘要
榆树井煤矿位于鄂尔多斯盆地西缘,属于毛乌素沙漠西北边缘软岩多煤层叠置区,地质、水文地质条件较复杂,煤层顶板的涌水溃沙为矿井的建设及生产带来了极大困扰。结合15煤的赋存特征及水文地质条件,重点采用基于地理信息系统(GIS)与层次分析法(AHP)耦合的“三图—双预测”法,开展15煤顶板涌(突)水条件综合分析,并编绘顶板涌(突)水条件综合分区图,有针对性的制定防治水措施,可为矿方15煤的安全采掘活动提供依据。
The Yushujing coalmine is situated in the western margin of Ordos Basin.The area belongs to Mu Us desert northwestern margin soft rock multiple coal seams superimposed zone with rather complex geological,hydrogeological conditions.Coal roof water and sand inrush bring about great complications in mine construction and production.The paper has combined coal No.15 hosting features and hydrogeological condition,focused to use GIS and AHP coupled“three maps-double predictions”method;carried out coal No.15 roof water inrush(bursting)condition synthetic analysis,and compiled roof water inrush(bursting)conditions synthetic zoning map,pertinently constituted water control measures,provided basis for coal No.15 safe winning and opening.
