It is feasible to predict the risk of outburst using IEERG, and it can be quantified.Īn F, Yuan Y, Chen X, Li Z, Li L (2019) Expansion energy of coal gas for the initiation of coal and gas outbursts. The larger the IEERG, the greater the possibility of outburst and the greater the intensity of outburst. ![]() This shows that the magnitude of IEERG is closely related to the outburst. ![]() Under the same gas pressure, the coal has the strongest adsorption capacity for CO 2, followed by CH 4 and N 2. The results show that with the increase of gas pressure, the IEERG increases gradually. In order to explore the relationship between IEERG and outburst intensity and verify the feasibility of the former in predicting coal and gas outburst, a series tests with different gases and different gas pressures were conducted on the basis of self-developed coal and gas outburst simulation system and IEERG measuring instrument.
