摘　　要：以某地下矿山采空区治理为工程背景,根据采空区规模、开采方式、围岩条件等,提出了顶底板围岩深孔爆破崩落治理方案,采用崩落的围岩充填采空区,并设计了合理的深孔爆破参数。经过精心设计和施工,成功消除了采空区安全隐患,保证了矿山安全生产,同时积累了空区治理的工程经验。Taking the goaf disposal of an underground mine as the engineering backgTound,accord- ing to the goaf scale, mining method and the surrounding rock conditions, the goaf caving disposal scheme of the surrounding rock of roof and floor of the goal based on deep hole blasting technique is proposed. The goal is filled with the collapsed surrounding rock, besides that, the reasonable deep hole blasting tech- nical parameters are designed. Through meticulous design and construction, the hidden dangers in the goaf area have been successfully eliminated,and the mine safe production has been ensured,besides that, the experience of goal disposal is accumulated.
