Abstract：In response to the bottleneck problems of delayed scanning operation,high labor intensity,and blind spots in the field of laser scanning in the current process of collecting information on the characteristics of explosive pile morphology,a method for sensing the characteristics of open-pit mine explosive piles based on unmanned aerial vehicle(UAV)survey technology has been proposed.Through a series of systematic studies,including the design of the explosive pile characteristic information collection scheme,material quantity calculation based on the explosive pile characteristic model,and fine verification of the explosive pile reconstruction model,a standardized operation process for the collection and analysis of explosive pile characteristic information has been proposed,achieving real-time,fast,and accurate collection of explosive pile characteristic information.Finally,through on-site experiments,the results show that the collection of explosion information can be shortened by more than 4 hours compared to previous on-site collection times,and the plane mean square error of the explosion reconstruction model is±0.13 m,and the elevation mean square error is±0.26 m,both of which meet the requirements of industry standards.
