摘　　要：　　随着采矿工艺技术发展,地浸采铀逐渐取代了传统的山地工程采矿,其基本原理是对 可地浸砂岩型铀矿按一定网度布置工艺钻孔,从注液孔注入地浸液,使之与铀进行充分反应,经 抽液孔提出地表,在地表工厂进行萃取铀的过程。地浸采铀与传统的山地工程比,地表破坏小、 形成的放射性废物和放射性核素的污染少、环境复原成本低,但也会对大气、土壤、地表水,特别 是对地下水造成一定的污染,必须采取一定的防护措施,否则会对环境及人们身体健康造成巨 大的危害。With the development of mining technique,in-situ uranium leaching has replaced the traditional opencut method gradually . Its basic principle is that the in-situ leachable liquid is poured into injecting drills and extracted from pumping drills after sufficient reaction with uranium ores. Comparing with traditional opencut methed,although in-situ leachable uranium mining method has the advantages of less surface destruction, less radioactive pollutant, low cost to environment restoration,it pollutes atmosphere ,soil and surface water ,particularly underground water.Therefore some measures must be taken to protect environment and human's health.
