洛肯(Lφkken)铜-辞-黄铁矿山的岩石力学研究始于1958年,并且在60年代后期,开发新的深部(700～1000m)阿斯特鲁普(Astrup)采区的过程中,岩石力学起到了重要的作用。基于岩石应力测量和力学性质研究,用光弹模拟实验确定矿房和矿柱尺寸,还模拟了不同的采矿顺序,以便找出适合于岩石力学和实际问题的解决办法。在伴随岩石力学研究的十五年采矿过程中,应用现场应力测量的方法,对应力大小进行了定期校核。近几年来,矿柱回收工作已经开始,岩石应力测量对于决定矿柱回采与否,起着重要的作用。高荷载的“关键”矿柱被预计出,并确定不回采,而无荷载或低应力矿柱可以回采。这项工作总的目的是为了获得全矿体80～85％的回采率。
Rock mechanics of the Lökkken copper-rhetorical pyrite began in 1958 and during the late 1960’s the development of a new deep (700-1000 m) Astrup mining area Rock mechanics has played an important role. Based on the study of rock stress measurement and mechanical properties, the photoelastic simulation experiments were used to determine the sizes of ore mines and pillars and different mining sequences were also simulated to find solutions suitable for rock mechanics and practical problems. During the fifteen-year mining process accompanied by the study of rock mechanics, the on-site stress measurement method was used to regularly check the stress magnitude. In recent years, mine pillar recovery work has begun, rock stress measurement for determining the pillar or not, plays an important role. High-load “key” pillars are expected to be determined not to be reclaimed, and no load or low-stress pillars can be reclaimed. The overall purpose of this work is to obtain a recovery rate of 80-85% of the whole ore body.
