近基础设施的爆破开采区安全性分析与控制

Safety analysis and control of mineblasting field adjacent infrastructure

结合长期开展爆破开采区保护对象安全性论证的实例,系统分析爆破振动对桥梁、隧道及边坡的影响以及相互间的力学关系。应用风险分析原理提出安全论证方法和控制危险有害因素的技术手段,并以划区控制爆破参数的普适工艺建立标准化的过程控制体系。

With mine-blasting field examples meeting the needs of protected object safety demonstration for a long time,systematically analyze the impact of blasting vibration on bridg-es,tunnels and slopes,etc.,and the mechanical relationships between each other. Using of risk analysis principles,it puts forward safety demonstrating method and hazardous factors control-ling technique,and establishes the common procedure of blasting parameters zoning control to realize a standardized process control system. The technology has been gradually improved af-ter several applications.
