【摘要】 介绍了煤炭地下气化的基本原理及气化产品的市场前景。重点分析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证明其本身就是一种天然的节能减排采煤方式。更多还原

【Abstract】 Describe the basic principle of underground coal gasification and market prospect of its products.Emphasize the low carbon feature of this technology,which specifically manifests in mining energy consumption,mining methods,increase of thermal efficiency.This feature is benefit for carbon capture and sequestration.It also plays an important part in energy conservation and CO2 emission reduction.The recycling of CO2,reduction of shaft engineering,CO2 emission of scrap mines as well as gangue hills’ spontaneous combustion,simultaneous mining of methane and coal all illustrate that underground coal gasification is a natural,energy-saving and low-emission mining method.更多还原
