Mechanism investigation on coal and gas outburst: An overview

International Journal of Minerals, Metallurgy and Materials, 2020
Coal and gas outburst is a frequent dynamic disaster during underground coal mining activities. After about 150 years of exploration, the mechanisms of outbursts remain unclear to date. Studies on outburst mechanisms worldwide focused on the physicochemical and mechanical properties of outburst-prone coal, laboratory-scale outburst experiments and ...

Study on Mechanism of Migration and Outburst of Natural Gas in Tunnel

Advanced Materials Research, 2011
The mechanism of gas outburst, gas-solid coupled simulation by discrete element method and natural gas problems in the Yuanliangshan tunnel are studied. Petroleum gas and coal gas are produces in the karst region generally; gas outburst includes coal gas outburst and the petroleum gas outburst in the tunnel construction.

Experimental Investigation on the Mechanism of Coal and Gas Outburst: Novel Insights on the Formation and Development of Coal Spallation

Rock Mechanics and Rock Engineering, 2021
The fragmentation of coal produces abundant coal gases and is presumed to be the defining characteristic of coal and gas outbursts. Knowing the mechanism of these catastrophic hazards is one of the most important breakthroughs in mining geology.

Mechanisms of Coal and Gas Outburst Experiments: Implications for the Energy Principle of Natural Outbursts

Rock Mechanics and Rock Engineering, 2022
Coal and gas outbursts in underground mines are the result of dynamic rupture propagation along coal seams, starting from localized instability caused by the sudden release of gas and strain energies. Although physical simulations have facilitated quantitative studies of outbursts, and rupture processes have been investigated both experimentally and ...

Mechanism of instantaneous coal outbursts

Geology, 2009
Thousands of mine workers die every year from mining accidents, and instantaneous coal outbursts in underground coal mines are one of the major killers. Various models for these outbursts have been proposed, but the precise mechanism is still unknown. We hypothesize that the mechanism of coal outbursts is similar to magma fragmentation during explosive
