摘　　要：临时矿壁的稳定性直接影响无间柱连续采矿技术的贫化率和损失率 ,进而决定该试验技术的成败。采用确定性分析法分析采矿结构的稳定性 ,由临时矿壁的力学分析建立临时矿壁的抗倾覆条件极限状态方程和强度条件极限状态方程 ,进行临时矿壁稳定可靠性分析 。The temporary ore wall exerts the direct control of the dilution rate and loss rate for non pillar continous mining method, and then it is decided that whether this experimental mining method is successful or not. The deterministic methods are generally used in stability analysis of mining structures. Based on deterministic methods, anti overturn limit state equation and strength limit state equation were established through a thorough mechanical analysis of temporary ore wall. The reliability analysis of this ore wall was conducted, and a few conclusions which were proved useful to mining engineering were obtained.
