逐孔起爆震动参数预报的BP神经网络模型

根据神经网络理论,结合逐孔起爆技术的特点,建立了爆破震动参数预报的BP网络模型。以某矿 山深孔台阶爆破为例,利用逐孔起爆过程中收集的原始资料和爆破震动监测数据,对建立的BP网络模型进 行了训练和应用。与实测值比较后发现,BP网络模型的预报结果更接近实测值。

A BP neural network model for forecasting of vibration parameters from hole-by-hole detonation

By combining the neural network theory and the hole-by-hole detonation technique,a back-propagation(BP) network model was established for the forecast of blasting vibration parameters.The deep-hole stair blasting in a mine was taken as the experimental object to train the established model by using the raw information and the monitoring data collected in the hole-by-hole detonation process.And the vibration parameters were computed by applying the empirical formula and the BP network model,respectively.Comp...
