摘　　要：为解决传统垂直深孔阶段崩矿嗣后充填采矿中凿岩硐室与底部结构需分别设计和分别施工的问题,通过改进凿岩硐室结构,使凿岩硐室既可作为下阶段矿块回采的凿岩硐室,又可作为上阶段矿块回采的底部结构,实现了凿岩硐室一结构多用途,从而达到降低生产组织难度、减少采切工程量、降低生产成本、保证工程安全的目的。In the traditional mining engineering,the structure and bottom of drilling chamber are generally designed and constructed separately. Alter the structure improvement,the drilling chamber can be not only used for stoping orebody at the foflowing stage,also as the bottom support of upper stoping,leading to the reduction in the complexity of production organization,cutting quantities as well as production cost without sacrificing project engineering safety.
