| 摘 要： | 在研究大量国内外矿井瓦斯涌出量预测方法的基础上,通过比较,分析灰色理论在矿井瓦斯涌出量预测方法中的优势,根据某矿102回采工作面的相关瓦斯涌出数据,以灰色预测理论为基础,通过对影响回采工作面瓦斯涌出量的关键因素分析,建立该工作面的瓦斯涌出量GM(1,1)预测模型,通过模型的求解,给出预测结果,并对结果进行检验.结果表明,该模型预测结果与生产实际吻合度较高,对煤矿瓦斯管理具有十分重要的指导意义.

| Abstract: | On the basis of the gas emission prediction methods in a large number of domestic and foreign mines,with comparison this paper analyzes the advantage of Grey theory to predict emission.According to the related gas emission data of a mine coalface 102 and on the foundation of Grey theory,the key factors of affecting the gas emission are found and the GM(1,1) protection model is built.By the solution to the model,the results can be given and tested.The result shows that it has a high degree of agreement with ... |
