【摘要】:我國煤礦瓦斯突出事故時有發(fā)生,造成的損失巨大;诖,對新常態(tài)下的瓦斯突出事故進行預警具有重要意義。通過研究近年來瓦斯突出事故發(fā)生狀況,選取煤層瓦斯含量、埋藏深度、厚度等十個關鍵影響因素作為評價指標體系,以獲取的18組數(shù)據(jù)作為研究樣本,借助SPSS軟件,運用因子分析——Logistic回歸方法進行綜合預警,另外18組數(shù)據(jù)作為檢驗樣本,結(jié)果都表明該方法有很好的預警效果,總體預警準確率達到80%以上。因此,該綜合預警方法可以較早預測煤礦瓦斯突出事故的發(fā)生。
[Abstract]:Coal mine gas outburst accidents occur from time to time in China, resulting in huge losses. Based on this, it is of great significance to warn the gas outburst accident under the new normal condition. By studying the occurrence of gas outburst accidents in recent years, ten key influencing factors, such as coal seam gas content, burial depth, thickness and so on, are selected as the evaluation index system. The 18 groups of data obtained are taken as research samples and SPSS software is used. The factor analysis-Logistic regression method is used for comprehensive early warning, and the other 18 groups of data are used as test samples. The results show that the method has a good early warning effect, and the overall accuracy of early warning is over 80%. Therefore, the comprehensive early-warning method can predict the occurrence of coal mine gas outburst earlier.
