The conventional on-site explosive mixing jumbo used in the Sa anshandao Gold Mine is not easy to operate and low in efficiency. By improving the sensitizing and mixing device at the end of the on-site explosive mixing jumbo and optimizing the intelligent remote control system suited to the operational characteristics of the jumbo, the issue of controllable adjustment of the loading density of on-site explosive mixing was resolved. These improvements also enhanced operational efficiency on-site, improved working conditions for personnel, and achieved the goal of reducing labor intensity while increasing efficiency. An industrial test was carried out on Level 1, involving the exploration drift at Sublevel l and stopes at Sublevels Il and III. The application results show that the excavation footage with singlt blasting in large-section drifts reached 4.2 m, and the blast hole utilization rate improved by 14.8 %, significantly boosting excavation efficiencey.
