注浆法在公路下伏煤矿采空区治理工程中的应用

Applications and studies about grouting on treating the gob areas of coal mine under highway

摘要: 根据我国近十年的工程实践,总结了高等级公路下伏煤矿采空区治理的机理和施工技术,以及治理的标准、采空区注浆治理的范围、质量检测等基本内容。分析与评价了煤矿采空区地面注浆技术的特点,提出了公路下伏煤矿采空区注浆治理存在的问题及解决的方法,以期为今后类似工程地质条件下的治理工程提供可借鉴的经验。

Abstract: Based on over ten years' engineering experiences,the basic contents such as treating mechanism,treating standard,grouting design,grouting technics,inspections on qualities act about grouting the gob area of coal mine under highway are discussed carefully.The characteristics about the grouting construction are analyzed and evaluated.In order to guide the similar grouting construction for the future,the present problems of treating gob areas of coal mine under freeway are raised.
