| 摘 要： | 以数字矿床为手段，进行资源三维定位、定量研究是危机矿山隐伏矿体找矿的新思路和新方法。在对可可托海3号伟晶岩脉的地质模型、成矿规律进行研究和总结的基础上，以Mincromine软件为平台建立了3号脉9个共生结构带的三维实体模型，并利用钻孔数据开展隐伏矿体的定位定量研究。结果表明。可可托海3号脉仍有较好的开发利用潜力，矿体中大于工业品住的BeO保有资源量60t,预测资源量63t。可为矿山的复采提供4～5年的资源保证。在矿脉的外围及深部，大于边界品位的BeO远景资源量1118t,Li20大于边界品位的资源量241t，显示3号脉具有良好的深入勘探开发的前景。对实例的研究也表明，基于数字矿床模型的研究方法在危机矿山找矿中具有独特的优势。

| Abstract: | To use digital mineral deposit models as a means to perform a 3D positioning and quantitative study of mineral resources is a new idea and way for looking for buried orebodies in crisis mines. Based on studying and summing up the geological model and metallogenic characteristics of the Koktokay No 3 pegmatite dike, a 3D model of 9 mineralogical-structural zones was constructed for the pegmatite dike with the Mincromine software as the platform, and then a positioning and quantitative study of buried orebodies was conducted by using drilling data. The results show that the Koktokay No 3 pegmatite dike has still potential of exploitation and that there are 60 t of remaining BeO resources with a BeO grade>commercial grade and 63 t of predicted BeO resources, which can provide a resource guaranty of 4-5 years for re-mining of the mine. In the surrounding areas of the ore vein and at depths, the perspective BeO resources are 1118 t with a grade>cutoff grade and the Li2O resources are 241 t with a grade>cutoff grade. These data indicate that the No 3 rare metal pegmatite dike still has great potential for exploration and exploitation. This study also demonstrates the unique advantage of the study based on the digital mineral deposit model in mineral exploration of crisis mines. |
