| Description | Coal and gas outburst is one of the most serious natural calamities in collieries. And protective layer mining is an effective regional method for preventing and controlling coal outburst. However, how to rationally determine with quantitative analysis the mining safety range in coal mining of protective layer is a difficult problem in rock mechanics and mining engineering. Then in this study applied solid–gas interaction mechanics for gas leakage flow, the solid–gas interaction numerical analysis for the safety range of up protective layer mining has been achieved with the results of experimental research and in-situ measurements so that the result of numerical simulations for the issue is closer to reality. Furthermore, the safety range of up protective layer mining can be determined with time-dependent based on the result of numerical simulations. Book Name: Rock Stress |
