某矿山深部开采回采进路参数的数值模拟分析
|
摘要
针对某矿山的深部开采,提出了3种不同规格回采进路断面积的回采方案,并运用FLAC3D软件进行数值模拟。通过对比分析各方案在巷道开挖后沿脉巷道顶板监测点位移以及回采进路开挖后其塑性区及最大主应力应力云图,最终选择断面为4 m×4 m的方案;通过将该方案模型与模拟矿山现场的模型进行监测点位移、塑性区及应力云图对比,验证了该方案能够满足矿山安全高效回采的要求。
Aimed at the deep mining in a mine,three mining schemes with different cross section areas of stoping drift were proposed,and the numerical simulation was carried out by FLAC3 D. By comparing and analyzing the displacement of monitoring points on the roof after the roadway excavation,as well as the plastic zone and the maximum principal stress nephogram after the stoping drift excavation,a scheme with section area of 4 m × 4 m was selected. By comparing the model of this scheme with the field model through analysis on the displacement of monitoring points,plastic zone and stress nephogram,it was verified that the scheme could completely meet the requirement of safe and efficient recovery of this mine.
