Gas emission under coal and gas outbursts

Journal of Mining Science, 2011
The paper considers the conditions of methane hydrate existence in coal seams. The authors estimate volumes of gas emission in a fractured coal layer upon a drop in gas pressure. The authors also give the assessment of outburst hazard of coal seam edge zone.
