中文摘要：
针对新疆喀拉通克铜镍矿高价值软破矿体的特点和试验开采环境再造连续采矿方法，并以顶板沉降量和塑性区范围为判据，运用FLAC^3D软件对人工项板预应力锚索支护进行模拟分析。设计3种锚网支护方案分别为：方案1，网度为4m×6m；方案2，网度为6m×8m；方案3，网度为8m×10m。通过比较各方案下顶板的沉降量、塑性区范围以及锚索最大轴力变化等参数，筛选出最佳支护方案。研究结果表明：方案1中顶板最大沉降量仅为4．24cm，塑性破坏区延伸高度小于7m，锚索最大轴力为16．59MN，且变化平稳，满足金属矿山安全规程和经济合理的要求，而其他方案结果参数均超出混凝土顶板的稳定性极限，由此得出方案1为最佳设计方案。
英文摘要：
According to characteristics of complex high-value deposit, the reconstructed environment and caving-successive were tested with backfilling delayed mining method. Using the displacement and plastic zone as the criterion, the stability of artificial roof was analyzed by FLAC^3D software. The three different types of net-degree cable shoring, i.e., type Ⅰ 4 m×6 m, type Ⅱ 6 m×8 m and type Ⅲ 8 m×10 m were simulated. These subsidence, disturbance band, plastic zone and axial force were analyzed. The results show that the maximum subsidence decreases to 4.24 cm, the height of plastic zones is less than 7 m, the maximal axial force is 16.59 MN and fluctuates smoothly in type ×. All these accord with mine security rules and economical requests, so type Ⅰ is adopted.
