摘要
瓦斯是煤矿的主要灾害之一,其发生事故的突发性、意外性和高危害性的特点和理论与实践的不完善,至今仍然是煤矿难以解决的问题。文章根据瓦斯涌出和运移的特点,结合矿井通风参数综合研究瓦斯防治问题。理论分析和实测研究表明,原生瓦斯的涌出与风压无关,积聚瓦斯涌出和运移的能量主要靠气体分子的内能以及外界给予的能量,瓦斯积聚与风速有密切的关系等。
Methane is one of the main disasters in coal mine. Because of characteristics on accidents sudden, accidents and high menacing and imperfections of the theory and practice, it is still difficult to solve the coal mine problem. Comprehensive study of methane prevention that based on methane delivery and movement characteristics, combining mine ventilation parameters. Theoretical analysis and experimental study shows that the original methane delivery has nothing to do with pressure, the energy of accumulation methane depends mainly on the gas molecules whhin and from outside sources of energy, close relationships of methane accumulation and wind speed.
