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。
According to seepage theory, this paper conducts an electrical simulation experiment on the problem of gas seepage around the drainage holes along the stope. At the same time, the gas pressure distribution around the borehole along the layer and the influence of different gas permeability coefficient on gas seepage are obtained. This is of certain reference value for studying gas drainage in coal seam and preventing coal and gas outburst.
