摘要
本文围绕原地破碎浸出采矿的工艺特点,针对主要工序之一的爆破筑堆,结合浸出工艺的物理-化学原理,从方案选择、筑堆效果及对矿堆的技术要求等方面,根据国内的首次实践和有关理论,进行了初步的分析和论述,并提出了挤压爆破的筑堆效应和在理论及实践上需完善的意见。
In this paper the author carries out the preliminary analysis and discussion for ore stacking by blasting,one of the main processes in stope leaching,from the aspects of the project selection,effect of ore stacking and the technical requirements for ore heap, around the characteristics of technology in stope leaching,combined with physical-chemical principle of leaching process and according to the first practice at home and related theories. The effect of ore stacking by tight-face blasting and opinions needed to improve in theory and practice are presented.
