地下深孔控制爆破安全综合技术的研究与应用

Research and Application of Underground Deep Hole Controlled Blasting Security Comprehensive Technology

爆破是矿山生产的主要工序之一,不仅作业风险度最高,对周边环境的影响度也最大,同时也是控制后续工作风险的基础。针对四川省芒硝矿山面临的安全生产共性问题,科学分析了爆破震源特性、振波传递规律和地表建(构)筑物的响应特性,建立爆破振动动力响应控制理论和工程设计方法,制定了工艺规程和相应的管理措施,形成系统的安全综合技术体系。5 a的普及与实践表明,该技术成熟,管理有效,安全有保障。

Blasting is one of the main processes in mining production, not only the operating risk is highest, but also has greatest influence degree to around environment, meanwhile, it is the basic of fol- low-up risk control. For the safe production~ common problems facing in mirabilite mine in Sichuan prov- ince, blasting earthquake source characteristic, vibro-wave transfer law and response characteristics of surface buildings （structures） were analyzed scientifically. Blasting vibration dynamic response control theory and engineering design methods were created, and technological procedure and corresponding management measures were developed. Then systematic safety comprehensive technology system was formed. Five years popularity and practice show that the technology is mature, the management is effec- tive, and the safety is secure.
