高速公路特殊路基煤矸石路段的灭火处理

摘要

分析了煤矸石自燃的必要条件，从去除煤矸石中的煤和黄铁矿、提供无氧环境等方面，探讨了煤矸石路段自燃的预防措施，同时提出了泡沫法、挖除火源、注水法等治理措施，以减少煤矸石路段自燃现象的发生。%The PaPer analyzes the necessary sPontaneous combustion conditions of coal gangue. Starting from asPects of demolishing coal Pyrite of coal gangue and Providing with oxygen-free environment,it exPlores sPontaneous combustion Preventing measures of coal gangue section,and Puts forward treatment measures,such as foaming method,excavating fire origin and water-injection method,with a view to reduce sPontaneous com-bustion at coal gangue section.
