煤炭地下气化是将埋藏在地下的煤炭直接变为煤气,通过管道把煤气供给工厂、电厂等各类用户,使矿井的地下作业改为地面作业,实现无人开采。自1912年,英国化学家威廉·拉姆斯在都贺姆煤田首先进行了实验,并用煤气发电后,煤炭地下气化得到了迅速的发展,世界各国对煤炭地下气化均相当重视,投入了大量的物力和人力来发展和完善这一新型采煤技术。 Coal underground gasification is buried underground coal directly into gas through the pipeline to the gas supply plants, power plants and other users, the mine underground operations to ground operations, to achieve unmanned mining. Since 1912, the British chemist William Rums first conducted experiments in the Tuho coalfield, and after using gas to generate electricity, underground gasification of coal has been rapidly developed. All countries in the world attach great importance to the underground gasification of coal and have invested A lot of material and human resources to develop and improve this new coal mining technology.
