description The utility model relates to the field of construction and ventilation of a tunnel, in particular to a multiple-working face ventilation structure for a long and large tunnel, which solves the problems of high construction cost, poor ventilation effect, high energy consumption and the like of a conventional ventilation structure. The multiple-working face ventilation structure comprises a left main tunnel, a right main tunnel and an inclined shaft, wherein cross passages are arranged between the left main tunnel and the right main tunnel; an axial flow fan with large air flow is mounted at the wellhead of the inclined shaft and communicated with the right main tunnel; two local fans are arranged at each of two cross passages II in the right main tunnel respectively and communicated with one tunnel face of the left main tunnel and one tunnel face of the right main tunnel respectively; wind-break walls are arranged among a cross passage I and other cross passages between the two cross passages respectively; at
