吴堡矿区主采S_1煤层覆盖层赋存特征

Occurrence characteristics of overburden strata of S_1 coal seam in Wubao mining area

陕北石炭二叠纪煤田吴堡矿区是陕西省唯一的大型炼焦用煤基地。通过研究S_1煤层结构、煤质特征、空间展布赋存条件、上覆盖层水文地质特征、顶板岩土的物理力学性质及工程地质特征,分析了煤层顶板稳定性及开采过程中存在的水文地质问题,可以为矿井设计、建设和生产提供参考。

Wubao mining area of Permo-Carboniferous coalfield is the only one large-scale coking coal base in Shaanxi Province. By analyzing the coal quality characteristics,physical and mechanical properties of surrounding rock,hydrogeological and engineering geological characteristics of S_1 coal seam,the seam roof stability and the hydrogeological problems in the mining process were researched. The results can provide reference for the mine design,construction and production in Wubao mining area.
