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.

Mechanism of multifield coupling-induced outburst in mining-disturbed coal seam

Fuel, 2020
Coal and gas outburst is a typical dynamic disaster occurring during coal mining. To analyze its multi-field coupling mechanism, in this study, a multi-field (including coal stress field, damage field, gas diffusion field and seepage field) coupling ...

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
