摘要
残矿回采是提高地质资源利用率的有效途径之一。以三山岛金矿曹家埠矿区高品位矿柱回采为工程背景,详细介绍了水压支柱工作原理、结构特征及功能特点;叙述了高品位矿柱在水压支柱为主要支护方式下的回采过程及效果。值得类似工程借鉴。
Remaining ores recovery is an effective way to improve the utilization rate of geological resources. The paper takes high grade pillars recovery in Caojiabu mining area of Sanshandao Gold Mine for engineering background, in detail introduces the working mechanism, structural features and functional characteristics of hydraulic prop. It also states the recovery process and effects when high grade pillars have hydraulic prop as their main supporting means, which can be consulted by similar projects.
