北辰矿10煤层瓦斯赋存规律及影响因素分析

Analysis on Gas Existence Law and Main Controlling Factors of 10th Coal Seam in Beichen Mine

针对北辰矿10煤层瓦斯赋存不明的状况,对北辰矿10煤层以往数据进行可靠性评价和分析,采用井下钻屑解吸法对煤层瓦斯含量进行补测,并用瓦斯地质法分析了影响北辰煤矿10煤层瓦斯赋存规律的地质因素。结果表明,北辰矿瓦斯呈"两端大,中间小"规律,且与埋深、构造和岩浆岩有密切关系。这对矿井通风设计及下一步的采掘部署,以及相应的瓦斯防治措施具有重要的指导意义。

In order to master the gas existence law,the past datum and their reliability are assessed and analyzed. At the same time, with the methord of drilling cuttings desorption, the content of coal seam methane is added in survey, and the geological factors are analyzed, which influenced the gas existence law of Beichen Mine. At last, the gas existence and distribution law of this mine are obtained and it would have important significance to the ventilation design and further mining and the corresponding deployment of gas prevention measures.
