摘要
在内蒙古某CO2+O2地浸采铀矿山开发中,发现Ⅰ-3、Ⅱ-4矿体平面上相互重叠,属于典型的多层矿化砂岩型铀矿体。应用独立构建浸采单元的方法,分别对每层矿体独立施工钻孔,研究对多层矿体同时进行地浸开采的工艺技术。试验共设计了18组浸采单元,分别对2层矿体独立开采。浸出运行试验表明,应用该方法同时开采多层矿化砂岩型铀矿效果较好,可推广应用。
In the exploitation of a mine in Inner Mongolia for CO 2+O 2 in-situ leaching,It was found thatⅠ-3 andⅡ-4 ore body were stacked on each other in a plane,which are belonging to the typical multilayer sandstone uranium ore body.The method of independent drilling hole is used to drill holes independently in each layer of ore body and study of the technology of in-situ leaching in each layer at the same time were carried out.The experiment of 18 groups of in-situ leaching units is designed to develop the two layers of ore body respectively.By analysis of the experimental data,it was found out that the method can produce better effects in the development of multilayer sandstone uranium deposit,which is worth wide promoted application.
