掘进面瓦斯动态涌出突出预警影响因素分析

Analysis of Influencing Factors of Gas Outburst Early Warning System Based on Monitoring Data of Gas Emission in Heading Face

为进一步提高瓦斯突出预警系统的准确性,对掘进面瓦斯动态涌出突出预警模型的计算结果与现场静态预测指标S、q、K1、Δh2进行了对比,分析各自变化不一致的原因,最终得出了影响预警模型准确性的主要因素。

To enhance the accuracy of the early warning system of gas outburst,the research solved the model of gas outburst early warning,which is based on gas emission monitoring data,and made a comparative analysis between the calculating results with static prediction index of S,q,K1 and Δh2,eventually the research reached the main factors influencing the accuracy of early warning model.
