Abstract
This report, Volume 3 of the 11-volume report on the master design simulator (MDS), describes the methane generator subsystem. This subsystem is used to determine methane emission rates into the mine environment. These flow rates are then used by the MDS in planning primary and secondary ventilation systems, planning a methane drainage system, and analyzing complex ventilation networks. Both steady-state and unsteady-state gas flows are included, and have been modeled as second order nonlinear partial differential equations. Finite difference equations are used to obtain numerical solutions to the models using a central differencing scheme. An application of the model is presented. The appendices include derivation of the gas flow equations used and a user's manual.
