瓦斯排放是煤炭开采是否安全的头等大事。煤矿传统采用的是将瓦斯由矿井通风直接排入大气的方式,这不但是对瓦斯这种清洁能源的浪费,同时也会造成空气污染。本文针对我国煤矿生产的特点和通风瓦斯的排放量、浓度等现状,结合当前国内外瓦斯综合利用技术的发展趋势,重点介绍了瓦斯氧化销毁、氧化供热和氧化发电三种瓦斯利用的新技术。并对其经济效益和市场前景作了初步分析。指出了瓦斯利用市场潜力巨大,经济效益、生态环境和社会效益可观。
Gas emissions is a top priority for the safety of coal mining. Traditionally, coal mines use the method of venting gas directly from the mine ventilation to the atmosphere, which is not only a waste of clean energy such as gas, but also causes air pollution. In this paper, according to the characteristics of coal mines in our country and the status of ventilation gas emission and concentration, combined with the current development trend of gas comprehensive utilization technology both at home and abroad, the paper mainly introduces the new technologies of gas methane oxidation destruction, oxidation heating and oxidation power generation . And made a preliminary analysis of its economic benefits and market prospects. Pointed out that gas utilization huge market potential, economic benefits, ecological environment and social benefits considerable.
