Abstract
The paper analyzes the danger of methane (CH4) and realizes the classification for coal mines of the Quang Ninh coal basin of Vietnam according to the methane category of Vietnam's safety standards for coal and shale mining. The relative methane emission and the relation between coal seam methane content and its change with depth at the Mao Khe coal mine are estimated. Using experimental data analysis to determine methane content at different mining depths and yield a set of equations which reflect the relation between methane content and coal seam depth, serve to predict the variability of methane content with the depth at the Mao Khe coal mine.
Keywords
methane hazard, relative methane emission, degassing, explosion of methane-air mixtures, Mao Khe coal mine
