摘要
分析了敏感指标临界值涵义和目前临界值确定存在的不足,采用"三率"分析法和基于隶属函数的模糊统计法来确定突出预测指标的临界值。结合"三率"分析法和隶属函数的模糊统计分析法的考察结果,并从安全角度出发,最终确定潘三矿C13-1煤层敏感指标的临界值为SL=5.5 kg/m,qL=4.4 L/m in。
This paper analysed the shortcomings of sensitive index critical value meaning and the current critical value,adopt ＂three-rate＂ analysis and fuzzy membership function statistical methods to determine the critical value of outstanding predictors.Combined with ＂three rate＂ analysis and membership function fuzzy statistical analysis of study results,and from a security point of view,ultimately determine sensitive indicator critical value is SL= 5.5 kg/m,qL=4.4 L/min in Pansan Coal Mine C13-1 coal seam.
