大红山铜铁矿区多层复杂矿体开采对象优化圈定研究

为了解决多层价值差异较大的矿体互层产出条件下开采对象合理选择圈定的问题,采用了三维数字化手段,通过建立矿床数学模型及价值模型,客观分析矿体价值及其分布规律,结合技术经济判据,合理优化、选择和圈定开采对象。本文的探索和实践,为类似矿床开采对象圈定和选择提供了有价值的思路和分析方法。

The Optimization and Delineation Research on Mining Object of the Multilayer Complex Orebody in Dahongshan Copper and Iron Mining Area

In order to resolve the reasonable selection and delineation problem of the mining objects under the interlayered ore body production conditions with the large multi-value differences, 3D digitalization is adopted; The ore body value and its distribution regularities is reflected and analyzed truly through the establishment of ore body geology mathematical model and economic value model, and combining with the technical and economic criteria, as well as the features that the fast ore delineation, fast calculation can be realized by ore body 3D digitalization, the multiple schemes comparison and selection is carried out, so that the reasonable optimization and delineation of mining objects is realized. The exploration and practice supply the valuable idea and analysis methods for the delineation and selection of the similar ore mining.
