近几年来,北京钢铁学院根据冶金部下达的爆破地震对环境的影响的研究课题,重点研究了爆破振动速度对矿区民房的影响,先后在首钢矿山公司所属的9个露天采场、石人沟露天铁矿、山东金岭铁矿和湖田石灰石矿等矿山,采用一套比较完善的测震系统,进行了大量的观测,收集了936个数据。通过综合分析,确定以爆破振动速度作为安全判据,提出了安全装药量、安全距离的计算方法,并在上述
In recent years, Beijing Institute of Iron and Steel according to blasting earthquake issued by the Ministry of Metallurgical Research on the impact of the environment, focusing on the impact of blasting vibration velocity on the mining area houses, successively in Shougang Mining Company’s nine open pit, Shirengou Open-pit iron mine, Shandong Jinling iron ore mine and limestone mine and other mines, using a relatively complete set of seismic system, a large number of observations collected 936 data. Through the comprehensive analysis, it is determined that the blasting vibration velocity is taken as the safety criterion, and the calculation method of safety charge and safety distance is proposed.
