中文摘要: 基于弹性力学、损伤力学以及应力波理论,通过岩体的物理力学参数、声学性质之间的数学关系,并结合不同判别条件,进而计算出较为贴近实际生产的爆破振动安全阈值。根据吉劳露天金矿现场爆破振动的监测数据,将矿区岩体的实际参数代入公式验算,研究结果表明,验算结果同爆破安全规程中的限值接近,故推导出计算公式简单易用,能够为边坡设计和控制提供参考。此外,从柱面波等理论推导得公式具有一定局限性,它仅仅适用于单孔爆破。
Abstract:Based on elastic mechanics, damage mechanics and stress wave theory, through the mathematical relationship between physical and mechanical parameters and acoustic properties of rock mass, and combining with different discriminant conditions, the blasting vibration safety valve value close to the actual production was calculated. According to the monitoring data of blasting vibration in Jilao open-pit gold mine, the actual parameters of rock mass in the mining area were substituted into the formula for checking calculation, and the research results showed that the checking results were close to the limit value in the blasting safety regulations, so the calculation formula was simple and easy to use, which can provide reference for slope design and control. In addition, the formula derived from cylindrical wave theory has some limitations, and it is only applicable to single-hole blasting.
