摘 要: 臨時礦壁的穩(wěn)定性直接影響無間柱連續(xù)采礦技術(shù)的貧化率和損失率,進而決定該試驗技術(shù)的成敗。采用確定性分析法分析采礦結(jié)構(gòu)的穩(wěn)定性,由臨時礦壁的力學(xué)分析建立臨時礦壁的抗傾覆條件極限狀態(tài)方程和強度條件極限狀態(tài)方程,進行臨時礦壁穩(wěn)定可靠性分析,得出了對實際工程有參考價值的結(jié)論。

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.
Key words: non-pillar continuous mining; temporary ore wall; reliability analysis; anti-overturn
