采用瑞典条分法、简化毕晓普法、推力传递法等三种方法,对会东矿露天西边坡稳定性进行电算分析计算,求出边坡上5个剖面的稳定性系数,并与许用稳定性系数比较,判断各剖面的稳定性。结果表明,西边坡存在不稳定区段,尤其是黑色破碎带作为重点治理对象,需采取必要的加固措施,以保证矿山安全生产。
The stability of open slope on the west side of Huidong Mine was calculated and calculated by using the three methods of the simplified method, simplified Bishop method and thrust transfer method. The stability coefficients of five sections on the slope were obtained, Compare the stability coefficient to judge the stability of each section. The results show that there are unstable sections on the west slope, especially the black broken belt as the key management object, and necessary reinforcement measures are needed to ensure the safe production of mines.
