Experimental Study of Coal–Gas Outburst: Insights from Coal–Rock Structure, Gas Pressure and Adsorptivity

Natural Resources Research, 2020
Coal–gas outburst is a complex dynamic phenomenon in underground coal mines that has occurred frequently over the past 150 years. This phenomenon has seriously restricted the efficient development of coal resources and it poses a great threat to global energy security.

3-D dynamic evolution analysis of coal-rock damaged field and gas seepage field during the gas extraction process

Journal of Natural Gas Science and Engineering, 2018
Abstract Coal seam construction disturbances or gas depressurization and extraction can cause rupture damage of the surrounding coal and rock. The damage not only changes the structural property and mechanical behavior of the coal and rock, but also changes the physical parameters of the coal and rock.
