摘要
本文建立了一个厚煤层分层回采时未采分层剩余沼气含量分布的数学物理模型,并在此基础上进行分析,导出其计算公式,并通过淮南、淮北两矿区部分矿井大量的现场沼气涌出资料确定公式中的待定系数。
A math-physical model is established of the distribution of methane remaining in the untouched part of a thick coalseam under slicing
mining. Based on that, theoretical analysis is made and formulae are derived for calculating the methane volume. With the related data obtained from mines in Huainan and Huaibei, the undetermined coefficients
n the formulae are worked out. A more accurate method for calculating the volume of methane released from coalseams being mined, mainly in mines with similar conditions in Huainan and Huaibei
