湘西金矿炼厂保安矿柱开采的岩石力学研究

Rock mechanics research on mining the safety pillars at smelting plant in Xiangxi Gold Mine

在金川二矿区，近年来深部的双中段回采形成了水平矿柱和保安矿柱。

In recent years , with the double-level mining at depth , horizontal jamb and vertical jamb had been formed .

仅南矿六中段以下，河床保安矿柱就占中段矿量的15～30%左右。

Only the safety pillars underlying the river bed below the № 6 level at South Mine account for 15-30 % of total ore within this level .

USING THE DISPLACEMENT DISCONTINUITY METHOD TO DETERMINE THE SAFETY PILLAR SIZE OF A SHAFT AND THE STOPE LAYOUT Mining Technology for Retreat the Protecting Ore Body under Jinyang Road

论文结合开阳磷矿金阳公路压矿的具体情况，对公路下的保安矿柱开采技术进行研究。

Based on the in-situ conditions of the ore body under Jinyang Road of Kaiyang Phosphate Mine , the relevant technology for retreating the ore body for protecting the road was investigated .

根据以上研究成果，从安全回采的角度，提出17~矿柱分步骤有限回采并留下永久保安矿柱的回采实施方案。

With the above researches work , the paper puts forward an implement project for the extraction of No ! 17 pillar that is to do it step by step restrictedly and leaving permanent protective pillar .
