马兰庄铁矿爆破震动测试分析

摘要

为评价马兰庄铁矿深孔爆破对采场200 m外村庄的影响，对马兰庄铁矿爆破震动进行了观测，分析了爆破地震波传播规律，微差爆破地震波叠加情况及爆破震动对居民心理的影响等，提出了减少爆破震动的方法和措施。%　　Abstract　To evaluate the effect of the deep hole blast on the villages 200 m away from Malanzhuang Iron Mine,the observation of the blast vibration in Malanzhuang Iron Mine was made，the propagation law of the blast－caused seismic wave,the seismic wave superimposition of short－delay blasting and the affect of blast vibration on the residents' psychology are analyzed.The method and measures for reducing the blast vibration are suggested.
