| Abstract: | In order to strengthen the gas emission gas monitoring of regional anomaly and advanced analysis work in part of Changping Company，provides an important adjunct for coal mine safety production，according to the Changping Company actual geological conditions，mining methods and measured indicators such as，this study determine the early warning index and critical value of Changping Company gas emission using "three ratio method"and other research methods，and the establishment of the gas outburst early warning system. Through the field investigation and the actual situation analysis，the gas content index A and the gas desorption index B can promptly and accurately the present and the future prominent danger，the critical value is 0.8 and 0.7 respectively. |
