Simulation Research on Distribution Rule of Gas in the Gob of Mines under the Sea

摘要

Recently, people pay much more attention to the research on gas movement law because more and more gas explosion accidents take place. The paper establishes mathematical model and simulate the distribution rule of gas in gob which is based on the air dynamic dispersion theory of the gob as well as the actual situation at H2103 fully mechanized coal face of BeiZao coal mine.
