The invention discloses a mine laneway generation system and a mine laneway generation method. The mine laneway generation system comprises a traverse point management module, a centerline management module and a laneway management module, wherein the traverse point management module is used for adding required traverse points on a mining engineering plan of a mine, and storing the measured information of traverse points in the mine; the centerline management module is used for generating laneway centerlines on the mining engineering plan of the mine according to the position information, imported by the traverse point management module, of the traverse points or an acquired laneway centerline drawing instruction; and the laneway management module is used for generating laneways according to selected laneway centerlines on the mining engineering plan and the parameter information of the laneways corresponding to the laneway centerlines; and laneway information corresponding to the laneway centerline comprises the input parameter information of the laneway or the parameter information of the laneway with the traverse points on the laneway centerline. By the system and the method, laneway drawing efficiency can be improved, and errors of the drawn laneway are reduced.
