| 摘 要： | 根据渗流理论,本文对沿层抽放钻孔周围的瓦斯渗流问题进行了电模拟实验研究。同时,获得了沿层抽放钻孔周围的瓦斯压力分布规律以及不同透气性系数对瓦斯渗流的影响情况等结果。这对于研究矿井煤层瓦斯抽放和预防煤与瓦斯突出等问题具有一定的参考价值。

| Abstract: | According to seepage theory, the gas seepage from drainage hole along coal seam is studied by means of electrical simulation experiment. Meanwhile, the distribution rules of gas Pressure around drainage hole along coal seam and the effect condition of differ nt permeability coefficient on gas seepage are described in the paper. These results are useful for studying gas drainage in the coal seam and for Prevention of coal-gas outburst in mines. |
