There are several methods (empirical, statistical, and machine learning tools) to calculate blast-induced ground vibration. Still, due to complications in the blasting procedure, under varying blasting loads and strata conditions, it is not easy to predict and simulate blast vibration precisely. Therefore, a study was conducted to simulate the field blast data in Ansys software using explicit dynamics. For this study, monitoring of ground vibration for 20 single hole blasts was carried out. The density of emulsion explosives was in the range of 0.9 to 1.15 g/cc. In the laboratory, rock properties were determined from the rock sample collected from the mine site before blasting. The in-hole velocity of detonation (VoD) and the density of the emulsion explosive were also determined. These parameters were used for numerical analysis to know the ground vibrations at specified points. The results of ground vibration predicted by the model are validated using field data.

使用显式动力学预测单孔爆破引起的地面振动

有多种方法（经验、统计和机器学习工具）可以计算爆炸引起的地面振动。尽管如此，由于爆破过程的复杂性，在不同的爆破载荷和地层条件下，精确预测和模拟爆破振动并不容易。因此，进行了一项研究，以使用显式动力学在 Ansys 软件中模拟现场爆炸数据。在这项研究中，对 20 次单孔爆破的地面振动进行了监测。乳化炸药的密度在 0.9 至 1.15 g/cc 的范围内。在实验室中，根据爆破前从矿场收集的岩石样本确定岩石特性。还测定了孔内爆炸速度（VoD）和乳化炸药的密度。这些参数用于数值分析以了解指定点的地面振动。模型预测的地面振动结果使用现场数据进行了验证。
