英刊“国际核子工程”最近(1980、4)报道了一个有关铀矿勘探所需开支的分配百分比。这是一个大致统计数字,是根据世界铀矿勘探的一般情况所提出的平均勘探成本统计。报道认为,提出一个统一的成本标准是困难的。但是,为各国铀矿勘探机构,提供一个参考性材料说明铀矿勘探成本的分配情况,各种开支在整个勘探工作中所占的比例(即百分比),是很有意义的。报道还认为,世界铀矿勘探是在各种条件下进行的,勘探项目的规模大小,费时的长短以及国际铀市场价格对勘探速度的影响,这些因素很不一样。又如各国的通货膨涨比例也不相同。就一般情况而言,在一个尚未进行工作的地区内对一个认为有价值的勘探点,进行2—3年的勘查工作(由踏勘到详勘完成),所需费用大致为20—200万美元。这些费用的分配,如下表:
The British magazine International Nuclear Engineering recently (1980, 4) reported a percentage distribution of expenditures on uranium exploration. This is a rough estimate of the average cost of exploration based on the general situation of uranium exploration in the world. Reported that the proposed cost of a unified standard is difficult. However, it is of great significance to provide a reference material for the uranium exploration agencies of all countries on the distribution of exploration costs of uranium deposits and the percentage (ie, percentage) of various expenditures in the entire exploration work. The report also believes that the uranium exploration in the world is carried out in various conditions, the size of exploration projects, the length of time and the impact of international uranium market prices on the exploration speed, these factors are very different. Another example is the inflation rate in different countries is not the same. As a general rule, 2-3 years of exploration work (from reconnaissance to detailed survey) at an exploration site that is considered valuable in an area that has not yet been completed may require an estimated cost of approximately $ 200,000-200,000 . The allocation of these costs is as follows:
