我国煤矿风排瓦斯利用的探讨

Research on the utilization of ventilation air methane in colliery in China

随着我国煤炭产量和开采深度的增加,煤矿的瓦斯排放量和风排瓦斯量正逐年增加。由于风排瓦斯浓度低,利用技术难度大,长期以来我国绝大多数风排瓦斯均未利用,而直接排空,这不仅严重地污染了大气环境,造成温室效应,同时也白白浪费了数量巨大的清洁能源。本文从治理和利用风排瓦斯的意义入手,介绍了风排瓦斯利用的重要性,阐述了我国风排瓦斯的利用现状和存在的主要问题,并对今后我国风排瓦斯的利用前景进行了展望。

With the increasing production of the coal mine and raising mining depth, the discharge of gas and the amount of ventilation air methane in colliery are also increasing year by year. Most of VAM is not utilized for a long time, and they were drain out into air directly, as the low gas density and they were difficult to utilized. It is not only pollute the atmospheric environment seriously, causing greenhouse effect, but also waste amount of purity power source. This thesis embark on administer and making use of ventilation air methane, the magnitude of utilizing VAM is introduced. And also expound the current situation of making use of gas and the major problems in utilizing the methane, and the perspective of utilizing VAM is imagined.
