摘　　要：为保证大煤沟露天煤矿边坡稳定,针对露天矿山开采过程各类型振动影响采场边坡稳定性问题,通过对影响露天矿山边坡稳定的三种典型振动类型产生的振动数据进行采集,并通过建模分析,结果表明爆破振动对边坡稳定性影响最大,频繁或长期在边坡坡脚爆破振动将会对排土场边坡造成破坏,降低边坡稳定性,并提出相应的治理方案和建议,为类似条件露天矿山边坡稳定防治提供一定参考。In order to ensure the slope stability of Dameigou open-pit Coal Mine,aiming at the problem that various types of vibration affect stope slope stability in the process of open-pit mining,the vibration data produced by three typical vibration types affecting open-pit mine slope stability are collected.Through modeling and analysis,the results show that blasting vibration has the greatest impact on slope stability,frequent or long-term blasting vibration at the foot of the slope will cause damage to the dump slope,the slope stability is reduced,and the corresponding treatment schemes and suggestions are put forward,so as to provide some reference for the prevention and control of slope stability in open-pit mines under similar conditions.
