含矿地质体体积法在江西德兴地区铜矿资源潜力评价中的应用

含矿地质体体积法是基于矿床模型综合地质信息预测技术基础之上的一种预测资源量估算方法，其核心算法是：预测资源量＝最小预测区面积×延深×含矿地质体面积参数×相似系数×模型区含矿系数。该方法显著的优越之处在于引用大比例尺精度的典型矿床及其深部和外围的预测资源量作为中等比例尺精度的模型区资源总量，从而极大地提高了模型区含矿系数的准确性，能够使预测结果明显趋于合理可靠。以江西德兴地区铜矿资源潜力评价为例，系统阐述了含矿地质体体积法的应用过程，预测2 000 m以浅铜矿潜在资源量767.11 万t。

Metallogenic Geologic Body Volume Method Applied in Copper Resource Appraisal of Dexing Area, Jiangxi Province, China

The metallogenic geologic body volume method is a resource appraisal method based on varied comprehensive geological informations of known ore deposit model. The algorithm is: the calculated mineral resources=minimum appraisal area×dip extension×area parameters of the ore-bearing geological body×similarity coefficient×ore-bearing coefficient of the model area. The obvious advantage of this method is that it quotes resource quantity of large known deposits as a guideline of resource quantity in the deep and periphery portions of the ore-bearing gological bodies in the appraisal area, thus greatly improving the accuracy of ore-bearing coefficients in model zone, and making the appraisal  result more reasonable and reliable.Taking the potential evaluation of a copper mine in Dexing area,Jiangxi as an example, the authors elaborate the application process of metallogenic geologic body volume method. 7 671 100 t of potential copper resource is estimated for above 2 000 m level.
