Application of Y+L Ventilation to Gas Control on 3303 Mining Face

Abstract:

Mine ventilation is one of the most fundamental measures preventing gas accumulation. Through analyzing the advantages and disadvantages of Y-type ventilation, the paper proposed and practiced Y+L ventilation after relevant study and investigation when traditional Y-type ventilation only could not solve the gas problem on workface of Hexi Mine, i.e. to adopt the technique of maintaining airway along roadway, arranging airway as the return airway on work face, and to dig the transportation roadway of the next work face n advance as the tail roadway of 3303 work face, so as to jointly form the Y+L ventilation pattern of the mining face. This method is applied to the gas control of 3303 work face.
