某铀矿床露天开采经济合理剥采比研究

Study on economic and rational stripping ratio of open pit mining in a uranium deposit

努和廷铀矿床矿体赋存条件与产状平缓的煤矿相似,地下开采技术方案和矿石选冶技术方案还需要深入研究。研究国内铀矿开采平均水平、矿床采出矿石品质、矿床所在地区差异、矿石最低盈利要求等因素,提出了针对努和廷矿床露天开采矿石"售价"的测算公式,采用考虑最低盈利要求的价格法计算露天开采经济合理剥采比是合适的。

The ore hosting conditions of the Nuheting uranium deposit are similar to those of the gentle production coal mines.The underground mining technical scheme and the ore dressing and smelting technical scheme need to be further studied.The calculation formula of the ore price of the ore in the open pit of Nuheting deposit is put forward,which takes into account the factors such as the average level of uranium mining in China,the ore quality of the deposit,the regional difference in the deposit and the minimum profit requirement of the ore and so on.It is appropriate to use the price method considering the minimum profit requirement to calculate the economic reasonable stripping ratio in open pit mining.
