摘要
针对高产高效工作面瓦斯涌出的特点,研究发现作为实验矿井的石泉煤矿高产高效工作面推进速度与瓦斯涌出量之间的规律,基于该规律我们提出动态分源预测法数学模型。运用传统分源预测法和动态分源预测法在石泉煤矿的邻近矿井高产高效工作面进行预测方法的效果检验,结果表明动态分源预测法提高了工作面瓦斯涌出量预测的精度。
According to the gas emission characteristics at high yield and efficient working face, the laws between the working face ad- vancing velocity and gas emission in high - efficient and high - yield Shiquan experimental Coal Mine are researched. Based on the laws, the mathematical model of dynamic source prediction method was proposed. With traditional method of different gas source and the dynamic prediction method in Shiquan Coal Mine of high yield and efficient mine working face adjacent effect of prediction method was inspected. The results show that the dynamic point source method can improve the prediction precision of the working face gas emission.
