基于低碳经济的煤炭地下气化技术

Underground Coal Gasification Technology Based on Low-carbon Economy

用数据说明了煤炭地下气化技术开采能耗的低碳化、开采方式的低碳化、热效率的提高以及有利于碳捕获与封存方面的特点,从而论证了其在节能减排中的重要作用。在开采方式中因为CO2的循环利用、减少井巷工程和减少报废矿井煤炭自燃和矸石山自燃、煤与瓦斯共采等优良特性导致其本身就是一种天然的节能减排采煤方式。

The characters of low carbonization of exploitation energy consumption,low carbonization of mining method,high heat efficiency and availing carbon capture and sequestration of underground coal gasification are illustrated by data in this paper,thus its important role in energy-saving and emission-reduction is demonstrated.The excellent characteristics including cyclic utilization of CO2,reduction of shaft engineering,reduction of scrap mines and spontaneous combustion in gangue hills,simultaneous mining of methane and coal make underground coal gasification a nature mining way of energy saving.
