瓦斯涌出量的模糊数学与灰色系统理论的预测

The Application Research of Fuzzy-Grey System Theory in the Prediction of Mine Gas Emission

矿井瓦斯涌出量的预测是典型的灰色系统，本文以灰色系统和模糊数学为基础，探讨了矿井瓦斯涌出量的影响因素，分析了灰色系统理论的不足，建立了符合实际的模糊灰色系统模型，并把时间序列改进成为影响因素序列，对矿井瓦斯涌出量进行预测。研究结果表明，该方法能较准确地反映矿井瓦斯规律。

The prediction of mine gas emission rate is the typical grey system. Based on the fuzzy-grey system, the affecting factors of mine gas rate are inquired into and the insufficiency of grey theory is analysed in this paper. Moreover, fuzzy-grey system model which is in conformity with actuality is set up and time sequence is turned into affecting factors sequence to predict mine gas emission rate.The results of research show that the methoed can reflect mine gas regulation.
