爆破振动是爆破主要有害效应之一。歪头山铁矿爆破振动对周围建筑物影响十分严重,使选厂主厂房南墙产生了长达20m、宽2～6cm的裂缝,过滤北墙角裂缝长达10m,精矿仓小屋产生多处裂缝;周围居民对爆破振动反应强烈,被迫停止生产爆破一个多月。为解决歪头山铁矿爆破危及正常生产问题,由冶金部安全环保研究院、本溪钢铁公司、歪头山铁矿、东北工学院承担科研任务,三年来先后通过现场调查,现场振动测量,实验室模拟
Blasting vibration is one of the main detrimental effects of blasting. The blasting vibration of Waituoshan iron mine has a very serious impact on the surrounding buildings, resulting in cracks of up to 20m in width and 2 ~ 6cm in width on the south wall of the selected factory buildings. Filtering cracks in the north corner of the wall up to 10m in length, Cracks; residents around the strong response to blasting vibration, was forced to stop production blasting more than a month. In order to solve the problem that the blasting of Waituoshan iron mine endangers normal production, the Research Institute of Safety and Environmental Protection of Metallurgical Department, Benxi Iron and Steel Company, Waitoushan Iron Mine and Northeastern Institute of Technology undertake scientific research tasks. Over the past three years, they have conducted field surveys, on-site vibration measurements, Room simulation
