摘要
分析了断层、褶曲、顶底板岩性、煤层埋深对矿井瓦斯赋存的影响,煤层埋深是控制瓦斯含量的主导因素,分析了矿井瓦斯地质规律,煤层瓦斯含量与瓦斯压力与煤层埋深一般呈线性相关。研究得出,位于矿井二1煤层埋深450 m处,瓦斯含量为3.89 m3/t。计算箕山井田瓦斯风化带深度为640 m,研究区全部处于瓦斯风化带内以及埋深与瓦斯压力和瓦斯含量的关系。研究为矿井瓦斯抽放的设计提供理论依据。
This paper analyzes the influence of faults,folds,roof lithology and coal seam depth on coal mine gas occurrence.Coal seam depth is the dominant factor controlling gas content.The gas geology of coal mines,coal seam gas content and gas pressure and coal seam buried deep is generally linearly related.It is found that the gas content is 3.89 m 3/t at the depth of 450 m inⅡ1 coal seam.It is calculated that the depth of the gas weathering zone in the Qishan Minefield is 640 m,and the study area is all within the gas weathering zone and the relationship between the burial depth and the gas pressure and gas content.The study provides a theoretical basis for the design of mine gas drainage.
