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 data shows that coal underground gasification technology low carbon energy extraction, low carbon mining methods, thermal efficiency and carbon capture and storage are conducive to the characteristics of the demonstration of its energy-saving emission reduction plays an important role. In the mode of exploitation, because of the recycling of CO2, the reduction of roadway engineering and the reduction of spontaneous combustion of coal in waste mines and spontaneous combustion of coal gangue, the coal and gas co-mining and other fine features lead to itself a natural energy-saving and emission reduction method of coal mining.
