摘　　要：以矿井回采工作面瓦斯涌出量预测为目的,基于单项预测模型选择偶然性及信息源局限性,首次全面系统地利用方差-协方差法、最优加权法及递归方差倒数法3种计算组合权重系数的组合预测模型方法进行单项和不同组合模型的运用及对比分析。In order to predict the gas emission quantity of the working iace in coal mine and based on the selection of contingency and the information limitation for single forecasting models, use variance- covariance, optimal weighting and recursive variance reciprocal these three weight calculation methods of combination forecasting models to the application and comparative analysis between single forecasting models and different combination forecasting models comprehensively and systematically for the first time.
