摘　　要：利用数值模拟技术,对地下开采与露天开采的相互影响进行了研究,模拟分析了露天边坡开挖爆破对地下采场的影响、地下采空区和地下开采爆破对露天边坡稳定性的影响。结果表明,针对不同的工况采取不同的安全技术措施,可实现露天开采和地下开采的安全生产。The interaction between underground mining and open-pit mining was studied by numerical simulation technology.The influence of excavation blasting of open-pit slope on underground stope and the influence of underground goaf and underground mining blasting on the stability of open-pit slope were simulated and analyzed.The results show that different safety technical measures for different working conditions can realize the safe production in open-pit mining and underground mining.
