摘要
针对煤矿采空区的副立井存在的安全隐患,提出了一种钻孔注浆填充采空区技术,在有限的施工量前提下完成9^#煤层副立井附近30 m范围内采空区的填充,实现了副立井周边环境的安全稳定。
Aiming at the potential safety hazard of auxiliary shaft passing through the goaf of coal mine,this paper puts forward a technology of filling goaf by drilling grouting.Under the premise of limited construction quantity,the goaf filling within 30 m around the auxiliary shaft of 9^#coal seam is completed,which realizes the safety and stability of surrounding environment of auxiliary shaft.
