摘要
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。
The 8101 working face of the Tashan Mine 4# coal seam is high - intensity mining face, since the mining, gas concentration has been frequently ovetxun. In this paper, the gas resource and gas emission laws are measures. Through the determination, the gas comes from the coal wall and the cut - off - coal, which accounts for 90% of the total gas emission. Gas Emission from the zone between No. 50 support and No. 105 support is the maximum, which should be focused on.
