Mining Publication: Development and Application of Reservoir Models for the Evaluation and Optimization of Longwall Methane Control Systems
Original creation date: June 2006
Methane explosions historically have been one of the major causes of fatalities and injuries in underground coal mining operations. Advanced numerical models and predictive modeling approaches have the potential to offer optimized methane control solutions for general mine planning purposes and to address specific methane-related operational problems. This paper describes the development of reservoir models for the longwall mining environment and their application for investigating the influence of various completion design parameters on the methane drainage effectiveness of gob gas ventholes. The influence of increasing longwall panel width on the effectiveness of current gob gas venthole completion and placement strategies in the Pittsburgh Coalbed was evaluated and optimized designs developed to capture the expected increase in methane emissions on the larger panel.
