Coal Properties And Mine Operational Factors That Impact Gas Drainage, Dennis J. Black, Naj Aziz

Faculty of Engineering and Information Sciences - Papers: Part B

Advances in coal production over the last 20 years have led to an increase in coal mine gas emissions. These gas emissions, if not effectively managed, may exceed the diluting capacity of the mine’s ventilation system resulting in gas concentrations in excess of statutory limits and the presence of an unsafe condition within the mine. Where such conditions exist it is typical for production to be slowed or stopped until such time as the rate of gas emission is effectively controlled and managed. This paper discusses the findings of a research project based on an underground mine operating in the …
