因素空间下的煤与瓦斯突出预测方法

Study on factor space-based prediction method of coal and gas outburst

煤与瓦斯突出的机理极为复杂。针对影响因素之间存在复杂的非线性关系,提出了基于因素空间下因素分析法的煤与瓦突出预测方法。因素分析法能更好地利用已有的数据,提取突出因果规则。该方法以典型矿井的实测数据为样本,提取预测推出的推理规则,并用其它样本数据进行预测推理规则进行验证。实际应用表明:该方法预测煤与瓦斯突出结果准确、方法可行有效。

Coal and gas outburst are governed by the underlying mechanism. As a response to a com- plex nonlinear relationship between influencing factors, this paper proposes the prediction method of coal and gas outburst based on factor analysis in factor space. Factor analysis method capable of using the ex- isting data and thereby extracting the causal rules of outburst works by using measured data of the typical mine as the sample for analyzing, calculating, and extracting the inference rules introduced by the pre- diction, and using other sample data to predict the inference rules to verify. The practical application shows that the method could provide a feasible and accurate prediction of coal and gas outburst.
