摘要
根据4103回采工作面的煤层赋存特征、瓦斯含量及工作面的瓦斯涌出,对采用的本煤层瓦斯抽采参数、采空区埋管瓦斯抽采参数以及高位瓦斯抽采钻孔的布置参数进行分析,并对采用的综合瓦斯治理技术效果进行分析,结果表明,回采面采用的瓦斯治理技术可以保证回采工作的安全。
According to the coal seam occurrence characteristics, gas content and gas emission of 4103 mining working face, this paper analyzes the gas extraction parameters of the coal seam, the gas extraction parameters of buried pipes in goaf and the layout parameters of highlevel gas extraction boreholes, and analyzes the effect of comprehensive gas control technology that adopted. The results show that the gas control technology adopted in the mining working face can ensure the safety of the mining work.
