Numerical simulation study on gas control in fully mechanized top coal caving face based on “U” downward ventilation

Aiming at the problem of over-limit gas in the return air corner of the “U” type downward ventilation fully mechanized caving face in Baode Coal Mine, the law of gas migration in the stope and goaf was studied. Using Fluent numerical simulation software and using the 81308 fully mechanized caving f...
