基于隶属函数的突出预测指标临界值确定

Determination of Critical Value of Outburst Prediction Based on Membership Function

摘要: 为了确定煤与瓦斯突出预测指标临界值，准确预测掘进工作面突出危险性。根据模糊集理论，通过对模糊统计数据的拟合，得出预测指标隶属函数曲线，研究预测指标的隶属度。研究得出，贵州容光矿业有限公司C₅煤层工作面预测煤钻屑瓦斯解吸指标△h₂临界值为180 Pa。

Abstract: In order to determine the critical value of coal and gas outburst forecast indicators, accurately predict the outburst of the heading face, according to the fuzzy set theory and fuzzy statistical data fitting, the paper obtains membership function curve of forecast indicators, and studies membership of forecast indicators. The study shows that the critical value of the coal cuttings desorption index(△h₂) of C₅ coal seam in Guizhou Rongguang Company is 180 Pa.
