The invention relates to the technical field of pipeline exhaust, in particular to a pipeline exhaust method and system for a coal-fired power plant. The method comprises the steps that pipeline parameters are obtained, and exhaust parameters of a pipeline are set according to the pipeline parameters; first exhaust operation is conducted on the pipeline according to the exhaust parameters, the real-time flow of the flow monitoring point is obtained, and whether an exhaust electric door at the exhaust point is closed or not is judged according to the real-time flow; if the exhaust electric door at the exhaust point is closed, the characteristic exhaust parameters of the pipeline are obtained, the exhaust evaluation value is generated according to the characteristic exhaust parameters, the next exhaust strategy is formulated according to the exhaust evaluation value, automatic exhaust operation is carried out after the exhaust parameters are set according to the pipeline parameters, and the second exhaust strat
