五家矿含水砂层下提高回采标高的可行性

Feasibility about raising the coal mining level under sand-water layer in Wujia coal field

    摘要
  • 摘要: 通过对五家矿区水文地质条件、煤层顶板、岩石物理力学性质进行分析和研究,提出在五家矿区含水砂层下采煤可以缩小防水煤岩柱,从而提高回采标高。

     

    Abstract: Based on the hydrogeological conditions,coal seam roof,rock mechanics in Wujia coalfield,author advance that safety pillar under water bodies can be shorted,mining level can be raised,and expound the way of construction.
