【摘要】：针对当前离子型稀土矿原地浸矿开采资源综合回收利用率低、环境污染严重等问题,从离子型稀土矿床地质条件、水文地质条件及工程地质条件3方面入手,制订了原地浸矿技术适用性对照表,采用极好、很好、好、一般、差、不适用等标度词评价原地浸矿开采技术适用性,并将原地浸矿划分为天然底板明沟集液法、人造底板暗沟网集液法、天然底板明沟+辅助巷道法3种采矿方法,指导离子型稀土矿山科学规划、有序开采。
[Abstract]:In view of the problems of low comprehensive recovery efficiency and serious environmental pollution of ion type rare earth ore in situ leaching mining resources, the geological conditions, hydrogeological conditions and engineering geological conditions of ion rare earth deposits are discussed in this paper. The applicability comparison table of in-situ leaching technology has been drawn up, which adopts excellent, good, good, general, poor and unsuitable scale words to evaluate the applicability of in-situ leaching technology, and divides in-situ leaching into natural floor Minggou liquid collection method. There are three kinds of mining methods of artificial floor dark trench net collecting liquid method and natural floor clear ditch auxiliary roadway method to guide scientific planning and orderly mining of ion rare earth mines.
