Analysis on influencing factors of open-pit mine throwing blasting based on random forest algorithm
In order to deeply investigate the main factors affecting the effect of thrown blasting,six factors affecting the effect of thrown blasting are systematically explored:rock properties,terrain conditions,geological conditions,blasting parameters,explosives characteristics and construction quality,and focusing on the controllable factors-blasting parameters are analyzed and researched in detail.The blasting design parameters of the site in previous years are selected,the target variable is the effective throwing rate.Random Forest Algorithm is used to analyze them.The results show that among the design factors of blasting parameters,the explosive unit consumption,row spacing and hole spacing have the highest importance.
