基于Madagascar的矿山微地震正演模拟

Forward modeling of mine microseismic based on Madagascar

矿山微震监测是一种新型的地球物理方法,通过分析不同复杂程度的矿井层状模型的微震波场特征,能够进一步了解微地震的传播规律。基于开源地球物理软件Madagascar,结合山东菏泽某煤田地层特征,建立不同复杂程度的矿井层状模型进行正演模拟,并对得到的波场快照和地震记录进行了对比分析。

Mine microseismic monitoring is a new type of geophysical method.By analyzing the characteristics of the microseismic wave field of layered models of mines with different levels of complexity,we can further understand the propagation law of microseismic.In this paper,based on the open source geophysical software Madagascar,combined with the stratigraphic characteristics of a coalfield in Heze,Shandong,a layered model of different complexity is established for forward simulation,and the obtained wavefield snapshots and seismic records are compared and analyzed.
