Abstract：In order to improve the accuracy of the gas outburst early warning technology, the recognition method of the characteristics of gas emission and its early warning effect was expounded in this paper, based on the optimization theory, the optimizing method for the early warning index and its critical value was established, and with the selection process of computers, the automatic determination of the early warning index and its critical value was realized. With this method, the inspection time for the early-warning index and its critical value was greatly shortened, the determination method for the early warning index was standardized, and the universality of the gas outburst early warning technology was thus improved. Better application effect of this method has been got in 81111 tailgate heading face in Pingshu Coal Mining Company.
