摘要
针对南方硬岩型低品位铀矿床存在采矿效率低、成本高的问题,以高昔矿床为例,在低品位矿石水冶工艺的技术改进和完善的支持下,通过对不规则、分散的矿体进行集合划分,探讨高效的阶段深孔空场嗣后充填采矿法。总结该采矿方法在应用中的技术措施、工艺特点、效果等,探讨该采矿方法在赣南低品位铀矿床的应用前景。
Aimed at problems of long term existed low mining efficiency and high cost in production of typical Gaoxi uranium deposit among southern hard rock with low grade of uranium deposit, also by support of the improvement and perfection of low grade uranium deposit hydrometallurgical technique through collection partition of irregular and disperse deposit, high efficient stage deep hole open stop- ing followed by back-filling method was discussed. Technical measure, technology characteristic, re- sult and experience of the method application were basically summarized. And application prospect in southern Jiangxi low grade uranium deposit was probed.
