The present invention discloses a feasibility determination method for upward mining of a pillar residual mining area by loading and unloading of a dynamic disturbance, and belongs to the technical field of coal mining. The feasibility determination method comprises the following steps of: firstly ascertaining a distribution location of the pillar residual mining area and the residual coal seam, obtaining a composition, a structure, physical and mechanical parameters of the interlayer rock stratum, and uniformly dividing and numbering the interlayer rock stratum from bottom to top; then determining the location of a control rock stratum, respectively calculating the magnitude of the disturbance load acting on the residual coal pillars and the control rock layers in the pillar residual mining area by a bearing pressure after propagation attenuation; finally analyzing the stability of the residual coal pillars and the control rock layers in the pillar residual mining area in consider ofthe effects of loading and unloading of the dynamic disturbance, figuring out the result of the feasibility determination for upward mining of pillar residual mining area. According to the feasibilitydetermination method for upward mining of the pillar residual mining area by loading and unloading of the dynamic disturbance, the situation that errors of empirical method are large is avoided, a theoretical basis for safety upward mining of the residual coal in the pillar residual mining area is provided, the recovery rate of the upper coal resource in the pillar residual mining area is improved, and the service life of a mine is effectively increased.
