The invention discloses a stress concentration-based outburst risk identification method for a coal roadway tunneling working surface and belongs to the technical field of coal mine safety. The method aims at solving the problem in the prior art that the outburst risk of the coal roadway tunneling working surface cannot be judged reasonably in the construction process. According to the method disclosed by the invention, main factors which influence the geological environment and the mining disturbance of the coal roadway tunneling working surface are quantified by adopting the stress concentration or superposition analysis method. A method for judging the stress concentration risk of the coal and the outburst risk of the gas is provided. Meanwhile, an important technical support is provided for the judgment of outburst risk-related stress concentration or superposition areas, and the outburst risk prevention of coal roadway tunneling.
