某铀矿山资源储量动态监测及资源利用研究

Dynamic Monitoring of Resource Reserves and Research on Resource Utilization in a Uranium Mine

以国内某铀矿山为研究对象,获取矿床地质勘查的钻孔位置、测斜、样品、岩性等基础数据,构建矿床三维地质初始模型、估算资源储量;根据矿床勘查、生产探矿和开采进展,对矿体/块段三维模型、资源量类型、开发状态等进行动态更新;构建不同时间矿床三维模型之间的逻辑关系,实现矿床资源保有量、变化量及变化原因的自动监测,掌握了矿山资源量家底;开展资源利用研究,计算当年和累计浸出率,结合矿山生产数据,预测矿体/块段可回采储量(证实储量),有针对性地提出矿体/块段资源利用方案,提高矿山的资源利用率。

Taking a domestic uranium mine as the research object,a three-dimensional geological initial model of the deposit was constructed by the basic data such as drilling location,inclinometry,samples,and lithology for geological exploration of the deposit,and the resource reserves of the deposit were estimated.According to the deposit exploration,production exploration,and mining processes,the three-dimensional geological model,resource types,and development status of the ore bodies/blocks were dynamically updated.The logical relationships among three-dimensional models of mineral deposits at different times was constructed to realize the automatic monitoring of mineral resource retention,changes,and reasons for changes,in order to grasp the background of mineral resource quantity.The research on resource utilization was carried out,the annual and cumulative leaching rates was calculated,the recoverable reserves(confirmed reserves)of ore bodies/blocks were predicted based on mining production data,and the targeted resource utilization plans for different ore bodies/blocks were proposed accordingly to improve the resource utilization efficiency of the mine.
