摘　　要：为了分析爆破作业诱发的振动对临近建筑物、设施设备造成的影响程度,采用爆破振动检测手段,对西湾露天煤矿连续进行8次爆破振动监测,每次布置测点22个,分别涵盖厂区内和周边建(构)筑物;依据爆破振动监测数据按照萨道夫斯基公式拟合确定了爆破振动速度衰减公式,并依据《爆破安全规程》确定了周边不同类别建(构)筑物安全振动速度允许值。监测结果表明:污水处理厂及厂内110 kV变电站处振动速度有超出限值情况,应重点采取减震措施。In order to analyze the impact of the vibration induced by blasting on adjacent buildings,facilities and equipment,blasting vibration detection means were used to continuously monitor the blasting vibration of Xiwan open pit coal mine for 8 times,with 22 measuring points arranged each time,covering the buildings(structures)in and around the plant area respectively;According to the monitoring data of blasting vibration,the attenuation formula of blasting vibration speed is determined by fitting according to Sadowski formula,and the allowable value of safe vibration speed of surrounding buildings(structures)of different types is determined according to the"blasting safety code".The monitoring results show that the vibration speed at the sewage treatment plant and the 110 kV Substation in the plant exceeds the limit,and vibration reduction measures should be taken.
