燃煤电厂粉煤灰在矿井回填中的综合利用分析

Analysis of ash and slag's comprehensive utilization of coal-fired power plant in backfilled of mine

大中型燃煤发电厂是固体废物产生的大户,每年产生大量的粉煤灰,并且有逐年增加的趋势,这些固体废物若弃之不用,不但占用土地而且浪费资源,而且会对环境产生极大的污染,发展大中型燃煤发电厂粉煤灰综合利用工程十分必要。近年来,粉煤灰应用于矿井回填技术在国内己经成熟并逐步推广使用。介绍了国内外粉煤灰矿井回填现状,并对矿井回填技术进行了简要分析。

Big and medium- sized coal- fired power plant produce lots of ash and slag and increases year by year. If these solids discard is throwed, not only wasting the resource but also pollution the environment. So it is very important for the big and medium - sized coal - fired power plant to develope Comprehensive exploitation of ash and slag. Recently, application of ash and slag in backfilled of mine in China has been mature and grad- ually promote the use of. It introduces the present situation of domestic and foreign in backfilled of mine, and brief analysis of mine backfill technology.
