| 摘 要： | 通过对张性断层处的应力、煤质变化程度分析,在张性断层控制区煤层瓦斯流动近似为单向流动,并通过瓦斯单向流公式,提出了张性断层的瓦斯压力控制边界计算公式,量化张性断层对控制区域煤层瓦斯压力的影响。采用该方法对宏松煤矿F2断层控制边界进行了计算,计算结果与现场实测结果基本一致。

| Abstract: | Trough the Change scope analysis of the stress and coal quality in Tensional faults,the flow of coal seam gas in tensile fault control area is approximately unidirectional flow.Through formula of gas unidirectional flow,computing formula of gas pressure control boundary in tensile fault was put forward and the influence of tensile fault on coal seam gas in control area was quantified.By using the method to calculate control boundary in F2 fault of Hongsong coal mine,the calculated result and measured result was basically same. |
