针对白银深部铜矿高应力环境下的深埋矿体,在深入分析采矿方法的基础上,进行了上向进路充填法进路回采顺序的优化研究,提出了适合上向进路充填法的3种合理进路回采顺序,并利用FLAC~(3D)进行数值计算分析。结果表明:3种方案中,一翼向另一翼“隔二采一”的方案,采场顶板应力集中程度最低、位移变化最小,采场稳定性程度最高,即为进路的最优回采顺序。当回采进路开采到第三步骤时,矿房顶板处应力不断积累产生明显应力集中区,此时易出现矿房顶板变形及冒落等事故,需采取相关措施,加强采场顶板的支护工作。
Based on the deep analysis of the mining methods, aiming at the deep ore bodies under the high stress environment of the silver deep copper mine, the optimization research on the sequence of the reclamation of the approach approach by the approach approach was put forward, and the suitable filling method for the approach approach Three kinds of reasonable approach to the mining sequence, and the use of FLAC ~ (3D) for numerical calculation and analysis. The results show that the scheme of one wing to the other wing and the method of “every second one and one” has the lowest stress concentration, the smallest change of displacement and the highest stability of stope, which is the optimal recovery of approach order. When the third step of the mining approach to the mining, roof stress at the mine roof continue to accumulate significant stress concentration zone, prone to roof deformation and Caolong mine accidents, to take relevant measures to strengthen the roof support jobs.
