Abstract
To evaluate methane explosion hazards in longwall coal mines, a CFD model was developed along with a 1/40th-scale, optically
accessible model of an underground longwall coal mining section. In this project, CFD models assisted in the design
of the physical model to ensure specifications were met for accurately representing the scaling physics as well as to assist
in narrowing the experimental matrix and identifying key locations for sensor placement to measure velocity, pressure, and
gas concentrations. This research will help develop strategies for methane monitoring that prevent methane ignitions and
explosions in longwall coal operations.
