Summary:The invention discloses a method for predicting coal and gas outburst danger. The coal and gas outburst tests are conducted on coal seams with different gas contents to obtain the critical gas dynamic phenomenon for non-outburst test and outburst test, and a value in the critical state the outburst critical value. According to the critical value, the outburst danger of a coal seam of any gas content can be determined.
