摘要
无烟煤层赋存大量瓦斯,论文通过数值分析出无烟煤吸附/解吸性能及瓦斯在煤层流动的规律,汝箕沟露天矿助燃物为瓦斯,对火区发展提供了物料基础,为瓦斯抽采起到理论支撑。
There is a lot of gas in anthracite coal seam.The paper analyzes the adsorption and desorption performance of anthracite coal and the flow law of gas in coal seam through numerical analysis.The gas is the comburant in Rujigou Open-pit Mine,which provides the material foundation for the development of fire area and plays a theoretical support for gas extraction.
