摘 要: 概述了新桥硫铁矿下盘高陡边坡体顺层单滑面剪切破坏、双滑面顺层剪切破坏、楔形破坏、溃曲破坏、崩塌等失稳的形式,分析了其发生灾变的内外原因,从工程设计、地表截排、地下疏干、实时位移监测等角度提出了边坡失稳变形的防范措施,为此类高陡顺层边坡条件下的开采安全提供参考。 In the paper the types of losing structure are summarized, that is single (double) slip-shear slide, wedge slide, burst slide, falling etc., the interior and exterior reasons of disasters are analyzed, and the precautions are put forward from the aspects of engineering design, flow drainage, underground unwatering and real time monitoring of displacement.
