Application of UAV 3D modeling technology in dynamic reserve monitoring of open-pit mines

针对无人机矿山测绘现有技术无法满足储量动态监测的精细化要求等问题,通过研究矿山多源异构数据融合、地形三维建模、矿体三维地质建模、精细储量自动计算方法,完成露采矿山储量无人机精细化动态监测系统的研发,实现了各矿种界内与越层越界精细动态储量的自动计算。应用结果表明,系统应用于矿体与矿界不规则露采矿山储量动态监测相对误差可达3%以内;能适应矿体与矿界不规则、地形变化大等复杂情况;成果可直观、准确展现矿山的开采状况;可显著提高露天矿储量动态监测的精度和效率。

Addressing the issue of existing mining surveying technologies not meeting the requirements for refined dynamic monitoring of reserves,an UAV fine dynamic monitoring system for open-pit mine reserves,which has a capability of automatically calculating the fine dynamic reserves within and beyond the boundaries of various minerals,is developed by studying the fusion of multi-source heterogeneous data in mines,three-dimensional ter⁃rain modeling,three-dimensional geological modeling of ore bodies,and calculation methods for fine reserves.The application results show that the relative error of the system can be within 3%;The system can adapt to complex situations such as irregular ore bodies and boundaries,as well as significant topographic changes;The results can intuitively and accurately display the mining status of the mine;Furthermore,this system can significantly improve the accuracy and efficiency of dynamic monitoring of open-pit mine reserves.
