国内光卤石矿物资源及其开采技术均不足,随着境外光卤石矿资源的获得,光卤石矿开采方法已成为我国钾盐开发“走出去”所面临的一大技术难题。根据光卤石矿床的地质特点并结合刚果盆地内某光卤石矿项目实例,就该类矿床采用钻井水溶法开采的适应性,以及与传统采矿法相比的经济合理性等进行了较为详尽的论证,结果表明,钻井水溶法开采可大幅减少矿山基建投资、缩短基建时间、增加可采深度、节约尾盐处理成本,而且采矿作业环境好、安全性高,值得在境外钾盐资源开发中创新应用。
Domestic carnallite mineral resources and mining technology are not enough, with the access of foreign carnallite resources, carnallite mining methods have become China’s potassium salt development “going out ” is a major technical problems. According to the geological characteristics of the carnallite deposit and the case of a carnallite project in the Congo Basin, the adaptability of the drilling water-soluble mining method for this type of deposit and the economic rationality compared with the traditional mining method are more detailed The results show that the drilling water-soluble mining method can greatly reduce the investment in mining infrastructure, shorten the construction time, increase the recoverable depth and save the treatment cost of the tail salt, and the mining operation environment is good and safe. It is worth to innovate in the exploitation of overseas potash resources application.
