摘要:
三山岛金矿采用传统现场混装炸药台车存在操作不便，效率较低的问题。通过改进现场混装炸药台车末端敏化混合装置及优化适合该台车工作特征的智能遥控装置等，解决了现场混装装药密度可控调节的问题，同时提高了现场作业效率，改善了人员操作环境，达到了减员增效的目标。选取一中段，于一分段探矿巷、二分段采场、三分段采场等开展了工业试验，应用结果表明：大断面巷道一次爆破进尺达到4.2 m，炮孔利用率提高了14.8 %，大幅提高了掘进效率。

Abstract:
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.
