煤层瓦斯压力是决定煤层瓦斯含量的一个重要指标。煤中吸附和游离瓦斯量的大小主要取决于煤层瓦斯压力。用间接法予测矿井深部瓦斯涌出量时,必须首先了解瓦斯压力沿深度变化的规律。瓦斯压力又是决定煤层煤与瓦斯突出危险性的重要因素。因此研究煤层瓦斯压力随深度的变化,对予测煤田深部瓦斯涌出量和煤与瓦斯突出危险性有着十分现实的意义。国内外的煤矿瓦斯研究人员多年来对这一问题进行过不少研究,其中大部分是对矿区特定的地质条件,根据实测煤层瓦
Coal seam gas pressure is an important indicator of gas content in coal seams. Coal adsorption and the amount of free gas depends on the size of coal seam gas pressure. When using indirect method to predict the gas emission in deep mine, we must first understand the law of the variation of gas pressure along the depth. Gas pressure is an important factor that determines the danger of coal seam and gas outburst in coal seam. Therefore, studying the variation of gas pressure with depth in coal seams is of great realistic significance for predicting the deep gas emission and the danger of coal and gas outburst in the coal field. Many domestic and overseas researchers of coal mine gas have done a lot of research on this issue over the years. Most of them are specific geological conditions of the mining area. Based on the measured coal seam watts
