A Computer-implemented Coal Mine Methane Model.
Proc 2nd SME-AIME Conf on the Use of Computers in the Coal Industry 1985 :378-387
A computer-implemented methane model for coal mines has been developed and undergone preliminary field testing. The model, built under contract, considers two-phase (gas and water) porous medium flow in two horizontal dimensions with an optional vertical equilibrium effect. The changes in permeability and porosity of the coalbed due to mining-induced stresses are considered, as are the effects of gas slippage, flow regime, and fluid compressibility. Computer code exercises of the one-dimensional version of the methane model are presented, as well as a history-matching exercise with the results of prior Bureau of Mines in-mine research.
