摘　　要：以新疆蒙其古尔P0线以西的矿床为研究对象,针对其矿体变化系数大、埋藏深、赋存条件复杂、规模化开发困难等问题,采用勘探钻孔与生产钻孔相结合的“探采结合”一体化模式,使勘探钻孔的利用率达到了61%,节约了钻孔投入成本,提高了资源质量,缩短了矿床建设周期,减少了植被破坏,做到了矿山绿色可持续发展。该技术经济效益及环境效益显著,为复杂砂岩地浸铀矿开发提供了新思路、新方法。Taking the deposit west of P0 line in Mengqigur,Xinjiang as the research object,aiming at the problems such as large variation coefficient,buried depth,complex occurrence conditions and difficult large-scale development of the ore body,the integrated mode of“exploration and mining combination”was adopted,which combines exploration drilling and production drilling,had made the utilization rate of exploration drilling reach 61%,saved the input cost of drilling and improved the quality of resources.The construction period of the deposit was shortened,the vegetation damage was reduced,and the green and sustainable development of the mine was achieved.The technology has remarkable economic and environmental benefits,and provides a new method for the development of complex sandstone in-situ leaching uranium ore.
