为了解决沉积岩体露天开采时的边坡稳定问题,根据岩体中软弱结构面的力学特性,分析总结了受软弱结构面控制的矿山软岩边坡稳定性的研究方法。探究了受控于软弱结构面的边坡的滑坡模式、计算方法以及强度指标的选取原则。对伊敏煤电公司露天矿南帮边坡稳定情况进行了实例分析,变形区边坡稳定性主要受四个泥岩弱层控制,采取内排压脚等控制开采的方法是有效的。
In order to solve the slope stability problem in coal mining, accoramg to me mecnanical cnaracters of weak structure plane in rock mass, the article analyses the stability analysis methods for soft rock slope controlled by weak structure plane. It also probes into the landslide mode, calculating methods and principles for parameter selection. The stability of south slope in Yinmin Coal and Electricity Company is analyzed and the stability of the slope is controlled by four weak layers and the restraining mining methods is effective.
