【摘要】 根据原地爆破浸出工艺特点和硬岩浸出的扩散传质机制,对影响浸出效果的矿石块度、裂隙发育程度(矿石孔隙度)、矿堆孔隙度和矿堆渗透性能等爆破筑堆质量特征作了分析和讨论,据此确定了筑堆质量要求,并提出了质量控制的技术措施。更多还原

【Abstract】 Based on the characteristics of stope leaching technology and the mechanism of diffusion and mass transfer in ore particle leaching,the quality features of ore stacking by blasting affecting the leaching effect are analyzed and discussed,such as particle size,ore cracks(ore porosity),porosity and permeability of ore stackingIn view of the above,the requirements on quality of ore stacking by blasting are determined and the technical measures for quality control of ore heap are presented更多还原
