The explosion of shrinkage method in Ganzhou uranium mine and to explore the use of in-situ leaching mining process

Stope leaching of uranium mining method compared with the conventional method, has the advantages of low investment, high efficiency and long mine (waste) stone reduced about 70%, less pollution, more suitable for the need of low cost uranium deposit mining. In recent years, with the deepening of mining, due to blasting heap, heap leaching of ore block, corner, pipe network and other key technical parameters of stope leaching of uranium stope limit, the heap appears low leaching rate, leaching cycle is long, the backlog of enterprise funds fatal weakness, affect the development of enterprises. In this paper, aiming at the existing problems of stope leaching, combined with the actual situation of a uranium mining, with the explosion of shrinkage method for optimization of stope leaching technology, reasonable and improve the recovery rate of resources, as the capacity to find a new breakthrough in uranium.
