摘要
分析了潘三矿11-2煤掘进工作面煤与瓦斯突出预测指标的敏感程度,采用双曲线模型构建了综合指标R1并确定了其临界值,将其应用在1492(1)掘进工作面中,结果表明:采用综合指标R1预测后,提高了预测突出准确率,减少了防突措施工程量的30%以上。
The paper analyzed the sensitive degree of the coal and gas outburst prediction index in 11 -2 seam gateway driving face in Pansan Mine. The double curve model was applied to set up the comprehensive index R1 and to set the critical value. The index and the critical value were applied to the 1492 （ 1 ） gateway driving face. The results showed that with the comprehensive index R1 to the prediction, the prediction correction rate of the outburst was improved and the outburst prevention engineering was reduced over 30%.
