摘要
随着伊敏露天矿采区转向,西端帮由工作帮转成非工作帮,其边坡角陡缓和边坡是否稳定,严重影响露天矿开采的经济效益及人员、设备安全。通过建立西端帮岩体工程地质模型,采用相似模型试验和数值模拟相结合的方法,开展边坡稳定及边坡角优化选取研究,确保露天矿山安全生产。
With the turn of mining area in Yimin Open-pit Mine, the western slope turned from working slope to non-working slope, whose slope angle and slope stability seriously affect the economic benefits in open-pit mine and personnel equipment safety. Through establishing the western slope rock mass engineering geological model, combining the similar model test with numerical simulation method, the author reserches on slope stability and optimal selection of slope angle to ensure production safety in open-pit mine.
