摘要
根据某岩金矿山开采技术条件及开拓工程布置情况,采用联合精细建模技术构建矿区三维数字模型,以历史数据为基础设置了可靠的初始边界条件,运用控制变量法研究两步骤采场跨度、分段高度条件下周边岩体及充填体应力和塑性分布规律,得出了合理的采场结构参数,即一步骤采场跨度为12m,二步骤采场跨度为18m,分段高度为15m。
According to mining technologies conditions and project layout in a rock gold mine, the three-dimensional digital mod- el of mining area was established by joint fine modeling technology. Based on historical data, the reliable initial boundary condi- tions were set up. Then, the control variable method was used to study the two-step stope span, as well as the distribution laws of stress and plasticity of surrounding rock and filling body under sectional height, which obtained the reasonable stope struc- tural parameters, namely that the first-step stope span was12 m, the two-step stope span was 18 m, and the sectional height was 15 m.
