采空区的二维正演数值模拟

Dimensional Numerical Modeling of Goaf

采用Emage-2D软件中的PW2D模块,建立了低阻采空区和高阻采空区的二维正演模型,并分别模拟分析了在采深、工作面斜长变化时的视电阻率变化规律。为采空区的探测提供了理论依据。

Using Image-2D software PW2D module, it established a two-dimensional goaf forward model of low resistance and high resistance. It simulated and analyzed apparent resistivity variation when the deep mining or face length changed. It provides a theoretical basis for goaf detection.
