Abstract：Against the backdrop of China's current management goal of"zero outburst"for coal seams and the new situation where regulatory authorities are placing greater emphasis on in-process and post-event su-pervision of outburst identification work,identification institutions have become increasingly rigorous and pru-dent in both the control of identification processes and the issuance of conclusions.This paper employs litera-ture review,case analysis,and on-site investigations to analyze the limitations of existing identification indica-tors and methods.It dissects critical issues such as the heightened risk of sudden changes in identification in-dicators due to dynamic mining activities,disputes regarding the delineation of identification scopes,challenges in accurate determining gas grades in adjacent outburst-prone coal mines,and shortcomings in the initiation procedures for outburst identification.To mitigate the potential risks these problems pose to coal mine safety and to enhance the reliability of identification conclusions,this paper proposes several countermeasures:strengthening the general survey of hidden gas-geological disaster-causing factors,closely monitoring and cap-turing outburst precursor information during the production process,implementing the"one working face,one strategy"prevention and control measures for transitional non-outburst coal seams,and adopting risk control measures for coal seam outbursts in deep mining.The above strategies can provide a reference for standardizing and scientizing the coal and gas outburst identification work,and are of great significance for im-proving coal mine safety production and promoting the revision and enhancement of national and industrial standards.
