In order to improve the intelligent level of drilling and blasting,reduce personnel work intensity,and improve the quality of drilling,the mine has transformed the existing Atlas Copco D45 open-pit down-the-hole drilling rig.By installing high-precision positioning systems on the drilling rig,inclinometers,depth detection sensors,vehicle-mounted intelligent terminals and other equipment,an accurate mathematical model has been established,combined with hole layout design software,digital mining software,and integrated with intelligent management and control platforms,realizing the automation and unmanned drilling of open-pit mine drilling rigs.
