Nonlinear Equations of Gas Seepage in Coal and Rock with Considering Adsorption Effect
ZHANG Zhigang
Abstract：Previous many studies showed that gas flowing in coal body was a nonlinear flow. In this PaPer,a nonlinear equation of gas seePage in coal and rock with considering the adsorPtion effect was established by using the self-designed coal and rock seePage ProPerty test device and the exPerimental methods. Based on the analysis of the mechanical characteristics of the nonlinear gas seePage in coal and rock,the influence of the adsorPtion effect on the nonlinear gas seePage ProPerties in coal and rock was exPounded. This nonlinear equation of gas seePage in coal and rock with considering the adsorPtion effect can be used for the study of the coal-seam gas flow theory and the develoPment of coal-bed methane.
