某露天磷矿爆破振动的影响分析

为确定某露天磷矿露天开采爆破振动的传播规律及对周围村庄民居的安全影响,对该矿不同采场的爆破作业振动进行了测试。对监测数据进行回归分析,找出了该矿爆破振动的传播规律及特征,判断爆破引起的振动不会对周围村庄民居产生不良影响,并就如何降低爆破振动影响提出了一些建议,为矿山今后的爆破作业提供了指导依据。

Analysis of Blasting Vibration in One Phosphorus Open-pit

In order to determine the influence of mine blasting vibration on the security of the structures of the near village and propagation law of blasting vibration, the author tested the blasting vibration in the quarry. By regression analysis of the in situ measured data, the propagation law of blasting vibration and its features were found out. A main conclusion was drawn that the near structures in the open-pit won＆#39;t be subjected to the effect of blasting vibration under the present scale of production blasting. Some advices on reducing the blasting vibration is proposed in this paper, and guiding principle basis was provided for future blasting.
