基于瓦斯涌出特征的煤与瓦斯突出预警是一种较为可行、有效的突出预测方法，其关键是确定合理、可靠的预警指标及其临界值。根据汪家寨煤矿实际煤与瓦斯突出特征及瓦斯地质条件，运用“列表法”、“临界域”理念、“三率法”等，对比分析了大量现场资料和所有瓦斯涌出特征突出预警指标计算结果，确定出符合汪家寨煤矿实际的瓦斯涌出特征突出预警指标及其临界值。现场考察及应用表明，所确定的预警指标合理、可靠，能准确、及时地反映工作面突出危险性，为矿井煤与瓦斯突出预测提供了有效的辅助分析工具。

The early warning of coal and gas outburst based on the gas emission characteristics is a feasible and effective outburst prediction method, its key is to determine reasonable and reliable early warning indicators and critical value of outbursts. In this paper, contrast analysis was made on a larger number of field data and all calculated results of the early warning indicators based on the gas emission characteristics according to the actual characteristics of coal and gas outbursts and the geological conditions of coal-bed gas in Wangjiazhai Coal Mine and by using the “list method”, “concept of critical region”,“three-rate method” and so on, the early outburst warning indicators and critical values conforming to the actual gas emission characteristics in Wangjiazhai Coal Mine were determined. The site inspection and application showed that the determined early warning indicators were reasonable and reliable, can accurately and timely reflect the outburst hazard in the working face and be used as an effective auxiliary analysis tool for coal and gas outburst prediction in coal mines.
