塔山煤矿山4#煤层8101工作面为高强度开采工作面,自开采以来,瓦斯频繁超限。为此,对该工作面瓦斯来源及涌出规律进行了实测。经测定,该工作面瓦斯主要来自煤壁及割落煤瓦斯,约占工作面绝对瓦斯涌出总量的90%,其中,位于50#支架至105#支架之内的瓦斯涌出量最大,应着重治理。 Tashan Coal Mine 4 # seam 8101 working face for high-strength mining face, since mining, gas frequently overrun. To this end, the face of gas sources and emission rules were measured. It is determined that the face gas is mainly from the coal wall and cut coal, accounting for about 90% of the total gas emission from the face, of which gas emission from the 50 # bracket to the 105 # bracket is the largest, Should focus on governance.
