摘要
文中采用单元法测定了15109综放面各个测点的瓦斯浓度,找出了工作面瓦斯浓度分布规律和各瓦斯来源涌出比例、石港矿综放面瓦斯治理难度大的主要原因工作面瓦斯涌出源多及邻近煤岩层瓦斯涌出量大。明确了初采期瓦斯治理应以邻近层瓦斯治理为主,并增加邻近层瓦斯抽采途径。
Unit method is used to determinate the gas concentration of measurement points of 15109 caving face in this test, and gas distribution law, the ratio of gas emission sources. Many gas emission sources and large volume of adjacent coal rock gas emission is the main reason of difficulty to gas control of fully mecha-nized caving face. Thus, giving priority to adjacent seams gas controlling in primary recovery stage, increas-ing approaches of adjacent seams gas extraction.
