摘要
南五区为唐山矿新采区,缺少可靠性瓦斯地质资料,而该矿为高瓦斯矿井,因此需要对其瓦斯地质特征进行研究。本文结合矿井地质特征,运用邻近区已开采工作面实测瓦斯涌出量资料,采用分源预测法和地质统计法对南五区5#、8#和9#煤层瓦斯涌出量分别做了预测。预测结果表明:煤层瓦斯涌出量随着埋深的增加明显增大,5#煤层瓦斯涌出量由3m3/t增加到6m3/t,8#和9#煤层瓦斯涌出量由5m3/t增加到7m3/t。
Owing to the lack of reliable gas geology data about Nanwu section,a new mining area of Tangshan Mine which has high gas content,it needs a research on its gas geology features.In this paper,based on the mine geological features and measured gas emission data of the working faces in near areas,different-source predicting method and geological statistics method have been used to predict the gas emission rate of 5#,8# and 9# coal seam in Nanwu section.The results show that the gas emission rate increases significantly with increasing of buried depth of coal seam: gas emission rate increases from 3 m3/t to 6 m3/t in 5# coal seam but increases from 5m3/t to 7m3/t in 8# and 9# coal seams.
