煤炭地下气化——回收报废矿井中煤炭资源的有效途径

Underground coal gasification: an effective way of recovering left-over resources in abandoned coal mines

介绍了世界煤炭地下气化技术的发展状况及我国利用该技术回收报废矿井中废弃煤炭资源的工业性试验 ,阐明了煤炭地下气化技术是回收废弃矿井中煤炭资源的有效途径 ,认为利用煤炭地下气化技术回收井工开采遗弃的煤炭资源技术上是可行 。

This article gives an introduction to the development status of underground coal gasification technology across the world and the industrial scale experiments with this technology to recover the left-over coal resources in abandoned coal mines in China This article holds that this is an effective way of recovering the left-over coal resources in abandoned coal mines The article also takes it for granted that the use of this technology for recovering the left-over coal left by underground coal mining operation is technologically feasible and economically rational
