【Abstract】 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.更多还原
