摘 要:通过室内岩石力学试验以及现场工程地质调查,确定了前常铜铁矿的工程岩体力学参数,并采用二维弹塑性有限元数值模拟方法,计算了前常铜铁矿由采矿引起的岩层移动,并得出其移动规律,圈定了岩层移动分级范围;同时,根据矿山技改实际要求,对技改采矿方案的结构参数、回采顺序以及回采高度等进行了比较计算,提出了优化的采场结构参数以及回采顺序和回采范围。The mechanical parameters of rock masses in Qianchang Copper - Iron Mine were determined by indoor rock mechanics test and engineering geology investigation, and the rock movement causing by mining was calculated by adopting two dimensions elastic - plasticity finite element method, resulting in the rules and grading areas of rock movement. Meanwhile, according to the mineg requirements of technical reformation, the structural parameters, stoping sequence and stoping high were calculated and compared, and the optimized stope's structure parameters, stoping sequence and stoping areas were suggested.
