摘要
八煤是徐庄矿四层可开采煤层之一,开采八煤遇到的最主要的威胁是下伏太原组灰岩的四灰承压水突出。文章运用"下三带"理论、斯列萨列夫公式、突水系数法对徐庄矿八煤底板临界厚度加以计算,并将这3个理论结合该矿水文地质条件进行分析比较,为安全、高效开采八煤提供较合理的前期研究成果。
No.8 coal seam is one of the four working seams in Xuzhuang Coal Mine, The most main threat is water bursting out from the underlying Taiyuan group limeston. This paper estimates No. 8 coal seam soleplate critical thickness by using ＂Three Underlying Belt theory, В.Я.Cлесарев formulae, water- gushing patameter method and compares the three methods with hydrogeological condition of Xuzhuang Coal Mine, in order to supply rational advanced research result for explorating No. 8 coal seam more security and efficiency.
