摘要
描述了吉林舒兰季德钼矿的矿床地质特征、水文地质、工程地质、环境地质条件及选矿试验结果。以该钼矿为例,系统讨论了三维矿产资源评价软件MICROMINE 11.03版的工作原理及流程,并对该矿床进行了资源量估算和验证。采用距离反比加权法进行资源储量估算,获得矿石量31374.14万t,钼金属量245096t,其中,111b+122b矿石量占总矿石储量的80.99%,钼金属量占总资源储量的81.08%;露天开采设计利用资源储量占总矿石储量的91.64%,钼金属量占总资源储量的91.99%。地质块段法和三角网多边形估算法检验结果表明,用三维矿产资源评价软件MICROMINE中距离反比加权法进行资源量估算,方法合理,相对误差较小,结果可靠。
The authors described the geological characteristics of Jide Mo deposit in Shulan of Jilin and its conditions of hydrology,engineering and environmental geology and their mineral processing experiment results.Taking this Mo deposit for example,the authors discussed the working principle and flow of 3D mineral resource evaluation software（MICROMINE） 11.03 edition,and also estimated and verified the resource reserves.The ore content is 313 741 400 t and Mo content is 245 096 t estimated by inverse distance weighting method.Among them,the ore content of 111b ＋ 122b accounts for 80.99 % of total ore amount,Mo content accounts for 81.08 % of total resource reserves;while the resource reserves used by opencast working accounts for 91.64 % of total ore amount,and Mo content accounts for 91.99 % of total resource reserves.The testing results of geological block and trianglation polygon estimation methods show that using inverse distance weighting method of 3D mineral resources evaluation software（MICROMINE） estimate resource reserves is reasonable,with small relative error and reliable result.
