原地爆破浸出技术在铀残矿中回收应用浅析

ANALYSIS ON APPLICATION OF STOPE LEACHING TECHNIQUE IN RECLAIMING REMNANT OF URANIUM

利用原地爆破浸出技术 ,针对特定的残矿赋存条件 ,采用特殊的爆破筑堆方法 ,并对不同的筑堆形式及爆破效果 ,采用适应的布集液技术 ,严格控制布液浸出制度 ,可在保证经济效益及安全生产的前提下以较小的工程和经费投入回收 5 0 %～ 6 0 %以上大量以各种形式存在的铀矿残矿资源。

Applying stope leaching technique,adopting special blasting means according to the specifically occurrence of remnant,and adopting corresponding technique of lixiviant applying and lixivium collecting and strictly controlling lixiviant applying system according to the different heap shape and blasting effect,50%～60% remnant resource of uranium can be reclaimed at the cost of little engineering and outlay,bases on the guarantee of profits and safe work.
