在许多情况下技术进步对经济指标的影响远远超过设计和研究中所必须考虑的其他一些因素的影响。例如,我们试比较一下技术进步和露天矿深度对剥离成本的影响程度。随着开采深度的增加,每1米~3的剥离成本也随着增长,这主要是由于运输费用增加的结果。同时,在技术进步的影响下,每1米~3的剥剥成本平均每年要降低4%。如果将采矿工程的延深速度取为10米/每年,则在开采深度、开采时间和剥离成本之间可以规定下列关系:
In many cases the impact of technological progress on economic indicators far outweighs the impact of other factors that must be considered in design and research. For example, let’s compare the extent to which technological advances and the depth of open pit mines affect the cost of stripping. As the mining depth increases, the cost of stripping every 1 to 3 meters also increases, mainly due to the increase in transportation costs. At the same time, under the influence of technological progress, the average cost of stripping per 1m ~ 3 is reduced by 4% on average every year. If the rate of deepening of a mining project is taken as 10 m per year, the following relationship may be established between the depth of exploitation, the timing of extraction and the cost of decontamination:
