Development of a model to predict peak particle velocity in a blasting operation

International Journal of Rock Mechanics and Minings Sciences, 2011
Ground vibrations arising from rock blasting is one of the fundamental problems in the mining industry, and predicting it plays an important role in the minimization of environmental complaints. To evaluate and calculate the blast-induced ground vibration by incorporating blast design and rock strength, artificial neural networks (ANN) and dimensional ...

Peak particle velocity of vibration events in underground coal mine and their caused stress increment

Measurement: Journal of the International Measurement Confederation, 2021
Abstract Peak particle velocity (PPV) is the most basic and direct parameter of vibration event to connect with stress increment, so they are studied in this paper through statistics and analysis. The vibration events in underground coal mine can be divided into whole mine (WM) event, working face (WF) event and heading face (HF) event, and the WM ...
