Paper Number: ISRM-ARMS8-2014-308
... was formulated for estimation of diffusion-capacity parameters (gas content, coefficients of diffusion and mass exchange) by the pressure measured in degassing borehole. The numerical analysis of cost function using synthetic input data revealed the necessity of the additional information on coal bed gas-kinetic...
