摘要
在简要介绍灰色关联分析理论的基础上,结合指标气体定性分析结果,运用灰色关联分析方法计算出不同特征温度范围内各气体指标与煤温的灰色综合关联度,并以此作为评价气体指标可靠度的量化依据。由定性、定量分析的结果优选并确定出各温度段内煤层自燃早期预报指标,为建立完善的指标气体体系、提高自然发火预报的准确性提供了切实可行的量化依据。
On giving a simple introduction to grey relative analysis theory combined with the results from indicator gas qualitative analysis,grey relative analysis method is used to work out the comprehensive grey relativeness between the various gases' indices within various temperature ranges and coal temperatures.This is then taken as criteria for quantitative analysis of the reliability of gas indices assessment.From the results of qualitative and quantitative analysis,the early prediction indices for coal seam spontaneous combustion within various temperature sections are selected and determined.This provides feasible quantitative grounds for the establishment of a perfect indicator gas system as well as improvement of accuracy of spontaneous combustion prediction.
