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 ,确定了筑堆质量要求 ,并据此提出了质量控制的技术措施。
The paper discusses and analyzes the quality features of ore stacking by blasting such as the ore lumpiness,crack growth extent(ore porosity),ore stack porosity and permeability of ore stack etc.that affect the leaching effect based on the process features of stope leaching and diffusion & mass transfer mechanism of hard rock leaching,defines the quality requirements on ore stacking and proposes accordingly the technical measures to control the quality.
