我国不少露天矿已逐步转入深凹露天。近十年来,深凹露天矿的一些不稳定边坡地段不断发生滑坡事故,影响安全生产。其边坡加固也从简单的削坡减载、清坡压脚、片石护坡挡墙,发展到大型锚杆、钻孔钢轨桩等综合措施。本文主要通过武钢大冶铁矿“(?)”号滑体的综合加固措施及后果,对该方法的特点、作用原理和观测手段等,作一论述。 (一)综合加固方法在大冶铁矿的应用 武钢大冶铁矿是一个大型深凹露天矿,
Many open-pit mines in our country have gradually shifted into deep and open air. In recent ten years, landslide accidents have occurred on some unstable slope sections in deep open pit mine, affecting safety in production. The slope reinforcement from simple cutting load shedding, Qingpo pressure foot, stone slope retaining wall, the development of large-scale anchor, drill rail pile and other comprehensive measures. This article mainly discusses the characteristics, principle of action and observation methods of the method by means of the comprehensive reinforcement measures and consequences of the “(?)” Slides in Daye Iron Mine of WISCO. (A) the comprehensive reinforcement method in Daye Iron Mine Wugang Daye iron ore is a large deep open pit mine,
