The Effect of a Tectonic Stress Field on Coal and Gas Outbursts [PDF]
The Scientific World Journal, 2014 Coal and gas outbursts have always been a serious threat to the safe and efficient mining of coal resources. Ground stress (especially the tectonic stress) has a notable effect on the occurrence and distribution of outbursts in the field practice. A numerical model considering the effect of coal gas was established to analyze the outburst danger from ...
