摘要: 矿体圈定是储量计算和采矿设计的基础,也是准确掌握矿体空间分布形态、有用矿物变化规律、矿石储量分布情况的重要依据。针对传统的矿体圈定方法带有浓厚的主观随意性、效率低等缺限,运用人工神经网络原理,提出基于神经网络的矿岩边界自动圈定,经实际验证能大幅度提高矿体边界圈定效率,很好地解决其他已有方法中存在的问题,其准确程度明显优于传统方法。

Abstract: Orebody delineation is the basis for reserve calculation and mining design and also an important basis for an accurate description of orebody spatial distribution pattern, law of valuable mineral change and ore reserve distribution.In view of the defects in conventional orebody delineation methods such as strong subjectivity and low efficiency, the automatic delineation of ore-rock boundary based on the artificial neural network technique was proposed.Its practical application has verified that the method can greatly improve the efficiency of orebody delineation and well solve the problems existing in other available methods, with the accuracy remarkably better than that of conventional methods.
