某采场大规模爆破施工振动监测分析

为评价某采场爆破作业对矿区永久性高边坡的影响程度，对爆破振动进行了实地监测。在需要重点监测的边坡位置，在距离爆心180，290，345，420 m的平台共设置了4个监测点进行爆破振动监测，并对监测数据进行了回归计算，得到了爆破振动衰减参数K、α值，并进一步确定了允许的最大一段安全起爆药量。研究表明：采用当前爆破方案不会对矿区边坡产生破坏性影响，为矿山爆破设计提供了可靠依据。

Monitoring and Analysis of Blasting Vibration in the Large-scale Blasting Construction in a Stope

In order to evaluate the impact of the blasting operation on the permanent high slope of a stope,the ground blasting vibration of the mine is monitored on the spot.For the slope position that needs to be monitored,four monitoring points are set up on the platform of 180,290,345,420 m from the blasting center,so as to monitor the blasting vibration,and the monitoring data is conducted regression calculation,the attenuation parameters (K and α) of blasting vibration are calculated,besides that,the maximum allowable amount of safe detonation charge is determined.The study results show that the current blasting scheme will not have a destructive impact on the slope of the stope,the analysis results can provide reliable reference for the blasting design of mines.
