| 摘 要： | 从露天矿山爆破扰动范围、振动速度以及数值模拟三方面综合了分析爆破对拟建隧道的影响.通过采矿境界平移达到爆破安全规定的要求,以保证隧道施工及运营阶段的安全.结果表明,在不满足现场测试条件下的情况下,上述三方面综合分析可以对矿山和隧道初步方案选定提供评估依据,为现场测试及同类矿山爆破设计提供指导.

| Abstract: | The influence of surface mine blasting on proposed tunnel wasanalysed from disturbance scope,vibration velocity and numerical simulation.The blasting safety requirements was met to ensure tunnel safety of construction and operation by mining boundary translation.The results showed that the comprehensive analysis above three aspects can provide assessment of preliminary program selected for mining and tunnel in condition of that site test requirement be not met,it can also provide guidance of field testing and similar mine blasting design. |
