【Abstract】 Aiming at the problem that it is difficult to accurately obtain the spatial motion trajectory of ore and rock in the blasting process of open-pit mine,this paper creatively puts forward a method to generate the spatial motion trajectory of ore and rock by using the high-precision MEMS inertial navigation sensor to collect the motion data of ore and rock in the blasting process at high frequency. Based on the inertial navigation technology,the generation algorithm of ore and rock trajectory in the blasting process is studied. Finally,the real spatial motion trajectory information of ore and rock in the blasting process is accurately output by using Matlab mathematical software,which provides a theoretical and technical basis for the study of ore and rock motion law in the blasting process of open-pit mine. Taking the-105 m horizontal mining area of Qidashan open pit mine of Angang as an example,the field test is carried out. Based on the test results,the ore and rock movement law of slag blasting is analyzed,which provides a reference basis for intelligent evaluation of open pit blasting effect.更多还原
