The invention belongs to the technical field of coal mine management, and discloses a mine pressure periodic weighting judgment method for a coal mine stope face, which comprises the following steps of: A, acquiring historical mine pressure data, and simultaneously acquiring mine pressure data of a current stope face; b, eliminating invalid pressure data of the current stope face; c, determining each coal mining circulation interval in the historical effective mine pressure data, calculating weighted working resistance and circulation end resistance of each coal mining circulation interval, and calculating a weighted working resistance basis and a circulation end resistance basis; d, determining each coal mining circulation interval in the current mine pressure data, calculating weighted working resistance and circulation end resistance of each coal mining circulation interval, and further determining the position of each pressure point of the current stope face; and E, calculating each weighting step pitch a
