煤矿通风瓦斯利用技术的潜力及经济性分析

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。

Potential and Economic Analysis of Ventilation Gas Utilization Technology in Coal Mine

Gas emission is the most important for safety production of coal mining .Using mine ventilation directly into atmosphere ,the traditional gas emission method not only wastes clean energy but also results in air pollu‐tion .Based on the production characteristics in coal mine ,emission volume and concentration of ventilation gas and combined with the developing trend of gas utilization technology at home and aboard ,the paper mainly intro‐duces three new gas utilization technology of oxidation destruction ,oxidation heating and oxidation power genera‐tion ,analyzes its economic effect and market expectation and points out great market of ventilation gas utiliza‐tion ,w hich has good economic effect and social benefits .
