摘要
小秦岭金矿为一超大型的含金石英脉型矿床,石英脉数量多、规模大、品位富,金的分布极不均匀,局部地段常形成特富矿段,对资源量的估算结果影响很大,因而需要对特富矿段进行合理的圈定和估算。资源储量估算时特高品位的确定和处理非常关键,不同处理方法得到的矿体平均品位和资源储量结果之间差别很大,直接影响到对资源量的合理性评价。
The Less Qinling gold deposit is a super-large gold-bearing quartz vein type deposit,in which there are a great number of large-scale quartz veins with high gold grade.The gold distribution is extremely uneven and some sections are very rich in gold,which greatly influences the calculation of gold reserves.Therefore,it is necessary to reasonably contour the extremely rich sections and to calculate their gold reserves.While calculating the reserves,the key problem is how to decide the extremely high grade and how to treat the extremely rich sections.Different treatment methods can obtain different calculated average grade of gold ores and different gold reserves,which will greatly influence the reasonable evaluation of the gold deposit.
