摘要
以顺兴露天矿北排土场北帮边坡为研究对象,应用简化Bishop法和传递系数法相结合,对排土场边坡稳定性进行了系统研究,揭示了坡角对边坡稳定性的定量影响,确定了不同排弃高度条件下的合理边坡形态与参数。研究结果表明,当边坡角增大时,顺倾露天煤矿北排土场北帮边坡稳定性近线性降低;滑坡模式为当排弃高度40 m时,稳定边坡角为22°,最终平盘宽度为37.4 m;当排弃高度60 m时,稳定边坡角为20°,最终平盘宽度为36 m。
Taking the northern slope in north dump of Shunxing Open-pit Mine as research object, applying simplified Bishop method and transferred coefficient method, the article conducted systematic research on the slope stability in dump, revealed the effect of slope angle on slope stability, determined reasonable slope shape and parameters under different abandoned height conditions. The results show： when the slope angle increases, the stability of dip bedded north slope of the north dump near linear decreases; when the abandoned height is 40, stable slope angle is 22°, the final flat plate width is 37.4 m; when the abandoned height is 60 m, stable slope angle is 20° and the final flat plate width is 36 m.
