以某大型露天铜钼矿为工程背景,结合生产现场实际情况,提出以爆破实体为空间约束进行插值的采矿模型技术思路,并进行了地质资源模型更新技术研究。研究结果表明:采矿模型技术不但具有快速、有效地实现局部或全部地质资源模型动态更新的性能,还可提高资源模型的精细化程度,并具有验证、修正和提高前期地质工作成果的作用。 Taking a large open-air copper and molybdenum mine as the engineering background, combined with the actual situation in the production site, the paper puts forward the technical idea of ​​mining model with interpolation of space constraint by blasting entity, and researches the renewal technology of geological resource model. The results show that the mining model not only has the capability of dynamically updating some or all of the geological resource models quickly and effectively, but also can improve the refinement of the resource model and has the function of verifying, correcting and improving the results of the previous geological work.
