Abstract
This thesis discusses the development and improvement of an empirical model---GASMAK2, that describes methane control requirements for the longwalling coal in gassy areas. This is not a theoretical model; it uses an empirically determined gas emission rate as an input. The computer program divides Longwall panels into segments, keeps track of the face advance and generates emission rates and volumes for both the entire panel and for individual zones within the panel. This model is Windows-based, uses the full capabilities of the Windows environment to provide a user-friendly program, and can aid in the determination of the number, size and location of methane control techniques that are needed for gob gas control. It is an excellent approximation, and the use of this model in conjunction with a careful data collection program should clearly indicate what future methane controls are needed.
