水泥矿山爆破振动的监测与分析
|
摘要
某水泥矿山附近有村庄和石砌危房,为确保爆破引起的振动强度小于石砌房屋的抗震能力和指导矿山安全生产进行了爆破震动测试。根据所测数据回归出了保护方向的爆破地振波传播规律和K、α值,并通过质点振动速度数据和爆区的推进情况,提出了后续爆破参数的改进和优化建议,为矿山爆破提供技术上的支持。
The residents of villages and the dangerous stone houses are near the cement mine explosion area,testing blast vibration to ensure that vibration from blasting cited seismic intensity less than the capacity of stone houses and guidance for safe production in mines.According to the regression test data protection to discovering the direction of propagation of blasting and K,α,through the particle velocity data and the explosion area to promote conditions,proposing suggestions for further improvement and optimization of blasting parameters,providing technical support to the mine blast.
