摘要
为加强长平公司部分瓦斯涌出异常区域的瓦斯监测和超前分析工作,为矿井安全生产提供重要辅助手段,根据长平公司实际地质条件、采掘方式、实测指标等,运用"三率法"等手段研究确定了长平公司瓦斯涌出预警指标及临界值,并建立了瓦斯涌出预警系统。通过现场考察及实际情况对比分析,瓦斯含量指标A和瓦斯解吸指标B能及时、准确地反映工作面当前和未来突出危险性,其临界值分别为0.8、0.7。
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 condi-tions,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.
