摘要
结合乌龙泉露天矿的生产实际 ,阐述了该矿深孔爆破震动的测试方法和测定结果。测定结果的分析表明 ,在当前的生产爆破规模下 ,爆破震动不会对主要建 (构 )筑物产生影响。通过测定数据的回归分析 ,得出了能描述该矿深孔爆破地震波衰减规律的表达式 ,为该矿预测生产爆破地震强度和采取降震、减震措施提供了理论依据。同时 ,对该矿的生产爆破提出了建设性意见。
In the light of its practical production, the monitoring method and results of deep hole blasting vibration in Wulongquan Open pit are expounded. The analysis on the monitoring results has shown that main constructions (or structures) in the open pit won't be subjected to the effect of blasting vibration under the present scale of production blasting. Through the regression analysis of monitored data, a formula of which can describe the attenuation of seismic waves from deep hole blasting in the open pit has been obtained, thus providing a theoretical basis for the forecast of blasting vibration strength and the adoption of vibration reduction measures. At the same time, some constructive views to production blasting in the open pit are put forward.
