| 摘 要： | 为了研究瓦斯有效抽采半径影响因素，测定了煤层透气性系数、煤层瓦斯吸附常数、煤的坚固性系数和煤的工业分析等煤层瓦斯基本参数，建立了均质煤层单孔抽采模型，采用COMSOL数值模拟软件，模拟了不同抽采时间下瓦斯压力变化规律、不同孔深和抽采时间下瓦斯压力变化曲线。研究为类似矿井瓦斯有效抽采半径的设计提供理论基础。

| Abstract: | In order to study the influencing factors of effective gas extraction radius，the basic parameters of coal seam gas such as permeability coefficient，gas adsorption constant，coal firmness coefficient and industrial analysis of coal were measured.A single-hole gas extraction model of homogeneous coal seam was established.The gas pressure under different extraction time was simulated by COMSOL numerical simulation software.The law of force change，the curve of gas pressure change under different hole depth and extraction time.The study provided a theoretical basis for the design of effective gas extraction radius in similar mines. |
