摘要
煤与瓦斯突出是一种极其复杂的动力现象,准确预测煤与瓦斯突出对煤矿安全生产尤为重要。根据井下实测的大量数据,采用现场数据统计分析并结合数值分析研究,确定了韩城桑树坪煤矿煤与瓦斯突出点预测的敏感指标是钻屑解吸指标K1,而钻屑量指标Smax和瓦斯涌出初速度指标q在研究区敏感性不明显。
The outburst of coal and gas is one kind of very complex power phenomena in colliery, and it is one severe nature hazard to producing coal safely. Based on a great number of data collected in underground mine, through count stat and numerical analysis data, the result is that sensitive index of predicting outburst point at Sangshuping Coal Mine is K1 index, and the Smax index and q index is not the sensitive index.
