摘要
工程爆破有害效应的控制对于周边环境具有重要意义。为确保某露天矿山附近风力发电机的安全,针对爆破振动和爆破飞石2种爆破有害效应,采用现场监测和回归分析的方法进行探究。结果表明:在现场爆破振动监测的基础上,得到了风机方向的爆破振动传播公式,确定了不同距离下的安全允许最大段药量;根据爆区与风力发电机的距离关系,划分了禁爆区和控制爆破区;提出了确保风机安全的爆破控制措施,为同类矿山安全生产提供参考。
The control of the harmful effects of blasting in engineering blasting is of great significance to the surrounding environment.In order to ensure the safety of wind turbines near an open-pit mine,field monitoring and regression analysis were used to explore the harmful effects of blasting vibration and blast⁃ing flying rock.The results show that on the basis of on-site blasting vibration monitoring,the blasting vi⁃bration propagation formula in the direction of the fan is obtained,and the maximum allowable safety dose at different distances is determined.According to the distance relationship between the blasting area and the wind turbine,the forbidden blasting area and the controlled blasting area are divided.The blasting con⁃trol measures to ensure the safety of the fan are put forward to provide reference for the safety production of similar mines.
