摘要
通过理论和数值模拟分析计算了木瓜井田9#,10#煤层上覆岩层导水裂缝带高度,论证了开采下组煤对地面淤地坝内水体的影响。
The height of hydraulic fracture zone overlying rock in No.9 and No. 10 coal seam in Mugua Coal Mine is analyzed and calculated by theory and numerical simulation. The influence of mining downward coal on the water bady inside the silt dam on the ground is expounded.
