摘要 本文从已知实例出发,认为矿区探明的标准储量和不同级别储量的勘查成本,应以各级别钻探工程投入系数来计算。C、D两级储量由于其成本差别不大,两者可合并计算。 Based on some current practice the article deems that the calculation of prospecting costs for demonstrated standard reserve and reserves of different categories in an explored area should be figured out by the input coefficients of their exploration. Costs for categories C and D can be jointly calculated as the disparity between the two is less distinctive.
