摘　　要：以煤与瓦斯突出预测为研究对象,选取地质构造、采深、瓦斯放散初速度等10个因素作为预测指标,应用距离判别分析方法建立了煤与瓦斯突出预测模型;结合实际数据,对预测模型进行训练和检验;将该模型用于实际,预测结果符合实际情况。The prediction of coal and gas outburst is taken as the research object. Ten factors such as geological structure, mining depth, initial speed of methane diffusion and so on were selected as prediction indexes. Prediction model of coal and gas outburst was established by using distance discriminant analysis method. The model was trained and tested with the practical data. Finally, the method was applied to example. And the prediction result accords with the fact.
