深部煤层瓦斯解吸规律的研究

Study on the Law of Gas Desorption in Deep Coal Seam

本文通过现场测定、实验室试验及模拟相结合的方法,对淮南矿区深部煤层的瓦斯吸附规律、煤壁瓦斯涌出强度及对不同变质程度与破碎程度下的残存瓦斯含量规律进行分析与研究,得出深部煤层的瓦斯解吸规律,用以指导深部矿井瓦斯灾害防治,对矿井安全高效生产具有重要意义。

By means of feld measurement, laboratory test and simulation this paper analyzes and researches the gas adsorption law, the gas emission intensity and residual gas content of different metamorphic degree and the degree of fragmentation. The gas desorption law is obtained in the deep coal seam, in order to guide the deep mine gas disaster prevention and control, which has important signifcance for the safe and effcient mine production.
