摘　　要：某新建小区紧靠已关停的采石宕口,宕口山体表面上存在大量危石、伞岩等隐患,且小区建设早于治理项目开工,给山体治理削坡工作造成较大阻碍。针对小区施工时遇到的山体上的一处伞岩,进行详细查勘和分析,合理设计爆破参数,采用深孔快速胀裂爆破进行处理,经实践,爆破效果良好,岩石裂而不散,可为类似工程的地灾治理提供参考。A new district is close to a closed quarry pit. There are a large number of dangerous rocks,umbrella rocks and other potential security hazard on the surface of the mountain at the pit. Because the construction of the residential area is earlier than the treatment project,great obstacles are encountered in the slope cutting work of mountain treatment.According to the umbrella rock on the mountain encountered in the construction of the district,detailed investigation and analysis are carried out,blasting parameters are reasonably designed,and deep-hole rapid expansion blasting is used for processing. The results show that the blasting effect is good,and the rock is split without scattering. It can provide a reference for the geological disaster treatment of similar projects.
