摘　　要：从露天矿边坡稳定性的影响因素及爆破振动机理阐述入手,依托矿山实例,提出爆破方案,在此基础上开展爆破振动测试,并对爆破振动作用下的边坡稳定性展开分析。研究结果表明,露天矿深孔爆破产生的振动会对边坡的稳定性产生一定影响,但并未造成边坡的安全系数大幅度降低,下降幅度在可接受范围内。由此可见,采用深孔爆破的方法开采露天矿合理可行。Starting with the elaboration of the influencing factors of the slope stability of the open-pit mine and the blasting vibration mechanism,relying on the mine example,the blasting scheme is put forward,on this basis,the blasting vibration test is carried out,and the slope stability under the action of blasting vibration is analyzed.The results show that the vibration produced by deep hole blasting in open-pit mine will have a certain impact on the stability of the slope,but it does not cause the safety factor of the slope to be greatly reduced,and the decline range is within the acceptable range.It can be seen that the method of deep hole blasting is reasonable and feasible.
