摘　　要：溜破系统是地下矿山基建期、生产期的关键工程,其关系着整个矿山生产系统的形成,影响着整个矿山的生产能力,对矿山日常生产稳定运行尤为重要。溜破系统结构复杂,上下联系密切,相互牵制,且各自掘砌工程量大,施工空间狭小,溜破系统如何在保证足够处理能力的情况下优化设计并快速施工成为首要任务。为解决这一问题,笔者以马城铁矿1号溜破系统为例,分析了影响产能和施工的主要因素,采用结构优化,节约了工程量1 376 m^(3),简化施工工艺,降低施工难度;采用措施工程,充分利用空间和时间,合理安排施工方案及顺序,引入掘支安相互融合的一体化施工技术,实现各工序有序协调,平行交叉作业,缩短工期6个月,加快了建设速度。Chute blasting system is key to the infrastructure and production of an underground mine. It affects the entire mining system and the capacity of a mine, and is particularly important for stable operation in a mine’s daily production. With complex structure, chute blasting system closely connected step to step. With big work quantity of excavation and masonry in small construction space, design optimizing and rapid construction of a blasting system while ensuring sufficient processing capacity have become a priority. In order to solve this problem, taking for the example of No. 1 chute blasting system of Macheng Iron Mine, main effects on the capacity and construction are analyzed. The structural optimization adopted saves 1,376 m^(3) of engineering volume, simplifies construction process, and reduces construction difficulty. Full use of space and time, rational construction plans and order, and integration of excavation, support and installment make various processes orderly and simultaneous which shortens the construction period by 6 months and speeds up the construction. The case is helpful.
