摘　　要：随着我国砂岩型铀矿床重叠矿体资源的增加,其开采方法的研究与试验已被重视,特别是重叠矿体分层分阶段开采。虽然该矿体地浸开采方法受各层资源分布及矿山规模、含水层与矿层之间的关系、各分层开采之间的衔接、钻孔使用寿命等多种因素的影响,但采用PVC封隔器的方法来施工钻孔,无论是先采上层还是先采下层应该都能得到实现。Along with increasing of multi-layer uranium sandstone deposits, investigation and test of mining technology have been seriously regarded, particular for separated mining at different stages. Although the mining is influenced by resources distribution in layers and mine capacity, relationship between aquifer and ore layer, mining sequence among layers, life of drilling hole etc. , the mining for multi layer sandstone deposits, no matter upper layer or lower layer is firstly mined, can be realized by use of PVC separator for well construction.
