摘要
为降低某露天水泥用灰岩矿爆破振动对周边民房安全稳定性影响,开展了相关的爆破振动监测及数据回归分析。结果表明通过对矿山的爆破振动数据进行拟合回归分析,探究爆破振动在黄家洼安置小区、街翁村、吕八村、马山洼村方向的传播规律,可得出矿山正常的生产爆破在黄家洼安置小区等4个方向民房处产生的爆破振动速度均小于《爆破安全规程》(GB 6722—2014)中允许振动速度,正常情况下不会对民房造成损坏。针对露天矿山被保护建筑物结构性质,提出最大同段药量和安全距离的限制值,将矿山爆区划分为控制爆破区和正常爆破区,从而实现了矿山安全开采,避免对周边设施造成影响。
In order to reduce the impact of blasting vibration of an open-pit cement limestone mine on the safety and stability of surrounding residential buildings,the relevant blasting vibration monitoring and data regression analysis were carried out.The results show that:through the fitting regression analysis of the blasting vibration data of the mine,the propagation law of the blasting vibration in the direction of huangjiawa settlement area,jieweng village,Luba village and mashanwa village is explored,and it can be concluded that the blasting vibration speed of the normal production blasting in the four directions of huangjiawa settlement area is less than the blasting safety code(GB 6722—2014),under normal circumstances,it will not cause damage to the residential buildings.According to the structural properties of the protected buildings in the open pit mine,the limit values of the maximum charge and the safe distance in the same section are put forward.The blasting area of the mine is divided into the controlled blasting area and the normal blasting area,so as to realize the safe mining of the mine and avoid the impact on the surrounding facilities.
