摘　　要：介绍原地爆破浸出与浅孔留矿联合开采法在西安中核蓝天铀业有限公司某采场的方案设计(穿脉和脉外天井、布液工程、落矿方式、爆破参数和器材)及实施情况(采场落矿、布液管线预埋、顺路天井架设、原地爆破浸出等)。这种联合开采法可实现高品位矿石出窿地表堆浸、低品位矿石就地爆破落矿筑堆浸出,并使布液均匀,浸出死角少,采场铀回收率提高(接近90%)。The uranium ores were mined by combined stope leaching and short hole shrinkage method in a stope. The scheme design（including cross road and rock raise, lixiviant distribution,the way of ore caving,and blasting parameters and equipment） and implementation（including the ore caving of stope, lixiviant distribution by buried pipes in advance, set up of square-set raise, and stope leaching）of the combined mining method are introduced. High grade ores and low grade ores can be mined respectively by the method. Mined high grade ores were sent to surface and processed by heap leaching method, and low grade ores were leached in place after blasting. The uniformity of lixiviant distribution was realized through buried pipes in advance,and the total recovery of uranium is about 90%.
