摘要
在归纳瓦斯监测数据异常模式的同时,从K线图角度对瓦斯异常模式进行研究,得出煤与瓦斯突出时呈大阳线形态,炮后瓦斯涌出呈二、三连阳等结论。据此确立瓦斯异常K线诊断准则,运用VB.NET程序设计语言编写了瓦斯异常K线诊断程序,通过对105条不同矿井瓦斯K线异常序列进行混合诊断,诊断准确率达到93.33%,普适性较强。
The gas anomaly pattern is studied from the angle of K-graph, at the same time, the abnormal mode of gas monitoring data is summed up. It is concluded that the coal and gas outburst is a big positive line, and the gas emission after the gun is two and three times positive. According to this, the diagnosis criterion of abnormal K-line of gas is established and the VB.NET programming language is used to compile the diagnosis program of abnormal K-line of gas. Through the mixed diagnosis of the abnormal K-line of gas in 105 different mines, the result shows that the accuracy rate is 93.33% and the universality is strong.
