Research of Response Characteristics of Elastic Wave Field in Two-Phase Media of Coal Rock

Abstract:

In order to study the characteristics of elastic wave field of the two-phase media of coal rock, a model of stratified two-phase media containing coal rock was proposed. A zero phase wavelet of higher resolution selected, a forward simulation of elastic wave field was performed on the model using MATLAB programming language. Simulation results show that the vibration amplitude of the elastic wave field, when propagating in homogeneous stratified coal rock media, vary with the variation of porosity, which indicates that it is feasible to utilize the elastic wave approach to detect the porosity of two-phase media of coal rock and has a certain significance in exploring the structural feature and pore property of underground water-contained coal rock.
