在煤矿开采中,采取相应的技术对瓦斯进行抽采,保证煤矿开采的安全是人们不断的追求,其中,低透气性煤层的瓦斯抽采比较困难,必须根据实际情况采取相应的技术措施处理。文章首先介绍了煤矿井下抽采技术,接着探讨分析了开采层、邻近层、采空区瓦斯抽采的相关问题,指出了其中需要注意的问题,提出了相应的瓦斯抽采措施,希望能够对实际工作提供借鉴和指导。
In coal mining, adopting the appropriate technology to extract gas to ensure the safety of coal mining is a constant pursuit. Among them, gas extraction from low permeability coal seams is more difficult and must be dealt with according to the actual situation. The article first introduces the underground coal mining technology, then explores and analyzes the related problems of the gas drainage in the mining floor, the adjacent floor and the goaf, points out the problems that need attention, puts forward the corresponding gas drainage measures, Practical work to provide reference and guidance.
