为了确定工作面突出预测敏感指标,通过研究演马庄矿与谢一矿掘进工作面电磁辐射特征,将电磁辐射预测指标(电磁辐射强度E)与常规突出预测指标R值指标及钻屑指标Δh2、K1、S等进行对比,利用灰色系统理论进行指标优选,比较各指标灰色关联度大小,结果表明,电磁辐射预测指标的综合关联度大于常规指标,预测无突出危险准确率为100%,可以作为工作面突出预测指标。
In order to determine the sensitive index of the prediction of the working face highlighting, the electromagnetic radiation forecasting index (electromagnetic radiation intensity E) and the conventional protruding prediction index R index and drill cuttings index Δh2 , K1, S and so on. The gray system theory is used to optimize the index, and the gray relational degree of each index is compared. The results show that the comprehensive relativity of the electromagnetic radiation forecast index is larger than the conventional index, and the prediction accuracy of the unobtrusive danger is 100% As a prominent indicator of the face.
