摘要
在世界能源消费结构上,煤炭占有重要的地位。但传统的煤炭开采利用方式不但严重污染环境,效率较低,仅能采出煤炭储量的15%左右,且伴随着地表沉降、工作环境危险、机械耗能高等不利因素。煤地下气化技术是将处于地下的煤炭进行气化产生煤气的一种清洁的能源利用技术。本文对煤地下技术的基本原理、发展背景以及关键技术的进展进行了分析和讨论,以期为煤地下气化早日实现产业化提供一定参考。
Currently,the coal is very important in the world＇s energy structure. The coal traditional utilizing way not only pollutes circumstance severely,but also has other issues including low efficiency（ only 15% to 20% of the total coal resources can be recovered in this manner）,land subsidence,high machinery costs,hazardous work environments,coal transport requirements,and so on. Underground coal gasification is a newer type of coal utilizing method that is being investigated and implemented around the world and that avoids most of the problems of coal traditional utilizing way. This paper reviews key concepts,development background and technologies of underground coal gasification,which can provide insights into this developing coal conversion method.
