摘要
本文首先分析讨论了采空区的地质特征及地球物理特征。从煤矿采空区的物性基础出发,阐述了利用地震波动法探测采空区的可行性,并根据波动方程原理,设计了部分采空区数学模型;运用正演模拟的方法,从地震波的运动学和动力学角度出发,分析了不同参数的采空区各自的地震响应特征及其分辨率;在前人有关采空区研究基础上,进一步研究了实际采空区的地震资料分析和研究。最后,结合实际资料总结了采空区在地震资料中的反映特征和识别标志。
At the beginning of the analysis we indicate the geological and geophysical property of the mined -out areas. Based on the physical property in mined - out areas, the paper formulated the feasibility of detection mined - out areas by seismic reflected wave method and worked out the mathematical model of partial mined - out areas according to principle of ray tracking and wave equation ; It analyzed the typical features of response in mined - out areas with different parameters by the means of simulating from the point of view of kinematics and dynamics; and the data of the mined - out areas is studied. In the end, it generalizes the reflection features and identifications of mined - out areas in seismic data linking up with practical facts.
