摘要
煤矸石是煤炭开发过程中的废弃物,利用矸石筑路是矸石综合利用的重要途径,但现行的路基设计施工规范中没有将矸石作为路基填料列出,工程中无标准可依,使用中存在不少问题。本文通过对矸石成分和矸石浸出液中有害物质分析,对矸石填筑路基的环境保护、路基压实标准、经济运距等方面进行了探讨。
Coal gangue is the waste in the process of coal mining, it is an important way of utilization to conduct roads. Through the analysis of hazardous substance in waste coal gangue and its leach liquid, this paper investigates the environmental protection of contructing roadbed, roadbed pressure standard,economic function and so on.
