The invention relates to a mining parameter optimization method for an underground low-ecological-damage working face. The mining parameter optimization method comprises the six steps of mine geological mining data collection, working face mining parameter initial value selection, experimental group design and development, subsidence prediction and damage grade evaluation of each experimental group, optimal experimental group selection and working face optimization parameter selection. According to the method, subsidence prediction and optimization selection of working face parameters are carried out by adopting a probability integral method which is maturely applied at present, so that the difficulty of data calculation operation during subsidence prediction evaluation is effectively reduced, and the normalization of calculation operation, the efficiency of data statistical calculation and the precision of subsidence prediction are improved; and meanwhile, an accurate reference basis is provided for evaluati
