The Optimization Research on Large-Diameter Longhole Blasting Parameters of Underground Mine Based on Artificial Neural Network

This paper combines with Kafang´s engineering practice of Xinshan mining area, makes crater tests, and then determines the blasting parameters under experimental conditions. Train the key stakeholders blasting parameters both at home and abroad based on the BP artificial neural network (ANN) model. On the basis that the best charge depth is 1.09 m which under the experimental conditions of blasting crater test. Conduct optimizing calculation of blasting parameters by using EasyNN-plus software. Through a comprehensive analysis of optimization ways and parameter error, recommend blasting parameters under experimental conditions: charge depth L=1.09 m, the best crater radius R_j=0.77-0.79 m, the best crater volume V_j=0.5-0.6 m³, and explosive consumption 1.0-1.1 kg/t.
