Abstract
Method for determination of outburst danger of coal beds includes drilling wells to coal bed, extraction of coal samples from those, determination through those samples content of physically bound moisture and methane, calculation of index of outburst danger and determination of outburst danger of bed through those. In the process of well drilling one in addition determines distance from surface of face of working to zone with maximal rate of gas liberation.
