The invention relates to safety production for disaster prevention and control of coal and gas outbursts, and provides a method for efficient shaft coal uncovering in a high gas mine in order to realize safely coal uncovering in a coal and gassy seam. The method comprises the following steps: (1) pre-estimation of coal seam occurrence through drilling holes; (2) item parameter determination and outburst prediction; (3) gas drainage under suction; (4) safely coal uncovering. In the invention, a coal uncovering implementation scheme is strictly and thoroughly prepared, and technical innovations for gas drainage under suction and blasting are made, so that disasters and accidents are prevented as much as possible; further, intensive fan drilled holes are adopted for large area control and efficient extraction of the seam gas, and uniform intensive dot-matrix-distributed blast-holes are adopted for safely coal seam uncovering, so that safely coal uncovering can be realized within a short time.
