| 摘 要： | 煤矸石场在自燃过程中会排放出大量有毒有害气体和烟尘,对周围大气和生态环境产生极大破坏。本文在分析研究区自然地理条件的基础上,通过钻孔注浆法对煤矸石场自燃进行治理,并对钻孔注浆法中的注浆液的材料选择和配制、注浆量和注浆参数的确定、注浆钻孔的钻进工艺、注浆工艺和治理效果检验方法等方面进行了深入研究,通过工程示范验证,取得了较好的自燃治理效果。

| Abstract: | During the coal gangue dump spontaneous combustion process will emit massive poisonous and hazardous gases and smoke dust,and produce great damage on peripheral atmosphere and entironment.Based on study area physical geographic condition analysis has carried out coal gangue dump spontaneous combustion governance through borehole grouting.Detailed study has carried out on drilling fluid material selection and formulating,determination of slurry volume and grouting parameters,grouting borehole drilling technology,grouting technology and governance effect inspection method etc aspects.Through project demonstration verification has proved preferable spontaneous combustion governance effect. |
