摘要

There is a long and unfortunate history of accidental explosions in underground coal mines in the United States. While safety controls have reduced the potential for methane explosions in the US, there still exists the potential for methane explosions if safe mining conditions are not maintained or an unforeseen accident occurs. Multiple analyses have been completed with various models being developed to help understand the potential impact of methane explosions. This paper establishes a methodology and presents initial results as part of ongoing research and testing to develop and validate a computational fluid dynamics (CFD) model to predict the potential pressures resulting from underground methane explosions. Full-scale field-testing results are compared to current full-scale CFD models to predict, analyze, and test the pressures resulting from underground methane explosions. Results indicate that, although there is some correlation between the established CFD model and field-test results, further improvement and verification of the CFD model remain warranted.
