Development and Application of Field Mixing Process and Intelligent Mixing Vehicle for Plateau Type Emulsified Explosives for Open Pit Mining

Abstract To improve mine production efficiency, reduce blasting costs, and meet the needs of capacity expansion, use an on-site mixing emulsion explosives truck for open pit iron ore deep hole step charging operation. This paper firstly briefly introduces process flow makes a detailed introduction to working principle control requirements each section production. Based on analysis basic adaptive control, PID controller is designed discharge temperature density achieve self-tuning parameters, which improves accuracy parameters product quality. The research results show that field explosives, operations personnel was reduced by 40% 50%, drilling workload about 7%. application technology effect, increases shovel loading reduces labor intensity workers, saves comprehensive mining cost temporary depot guarding disposal used packaging in mines.
