煤矿回风井掘进爆破振动监测分析

Coal Mine Return Air Shaft's Excavation Blasting Vibration Monitoring and Analysis

以某煤矿风井爆破掘进为研究对象,对回风立井和进风立井爆破掘进开挖所产生的地震波进行了监测和分析,利用萨道夫斯基公式确定K、α值,并结合实际情况调整爆破参数,以此来保证地面建筑物(构筑物)的安全。

Taking the excavation blasting of a certain coal mine＇s return air shaft as the research object, this paper monitors and analyzes the seismic wave produced in the excavation blasting of return air shaft and air-intake shaft, and determines the values of K and a by using the Sadovs Vibration Formula, and connecting with the actual situation, adjusts the blasting parameters so as to ensure that the ground buildings＇ （structures＇） safety.
