摘要
文章通过对煤层瓦斯存在形态、采空区瓦斯分布规律和矿压显现对煤层瓦斯存在形态及采空区瓦斯分布影响进行定性分析,解释矿压显现对工作面风流中的瓦斯浓度变化原因。为煤矿瓦斯管理及工作面周期来压的预测预报提供科学理论依据和方法。
Through the qualitative analysis of existing status of coal seam methane , goaf methane distribution law, effect of strata behaviors on coal seam methane existing status and goaf methane, effects of strata behaviors on methane concentration in air flow is explained , thus providing scientific theory and methods for mine methane management and prediction and forecasting for coal face periodic pressure .
