%X 针对某煤矿的瓦斯涌出量快速预测问题，提出了采掘瓦斯平衡系数，采用分源比例法，在布置回采巷道阶段可以预测采区瓦斯涌出量。通过分源比例法预测出的采区瓦斯涌出量回采时为7.36 m3/min，检修时为5.80 m3/min，实测值回采时为7.81 m3/min，检修时为6.18 m3/min，误差控制在15%以内。本研究为煤矿瓦斯涌出量快速预测提供了理论依据和实践基础。
Aiming at the problem of rapid prediction of gas emission in a coal mine, the gas balance coefficient of mining and excavation is proposed. The gas emission in the mining area can be predicted by using the sub-source ratio method in the stage of arranging the mining roadway. The gas emission in the mining area predicted by the source ratio method is 7.36 m3/min during mining, 5.80 m3/min during maintenance, the measured value is 7.81 m3/min during mining and 6.18 m3/min during maintenance. The error is controlled within 15%. This study provides a theoretical basis and practical basis for the rapid prediction of coal mine gas emission.
