摘要
煤层瓦斯含量是计算矿井瓦斯储量和预测瓦斯涌出量的基础,也是预测煤与瓦斯突出的重要参数之一。结合某矿的瓦斯基础参数,通过编制敏感度分析表和敏感度分析图,对煤层瓦斯含量进行了敏感度分析,并且计算了各个敏感因素对于瓦斯含量的敏感系数以及临界点,确定了吸附常数a、水分等敏感性因素的临界值。
Coal seam gas content was the basis for calculating mine gas reserves and predicting gas emission,and is also one of the important parameters for predicting coal and gas outburst.Combining with the basic parameters of gas in a mine,sensitivity analysis table and sensitivity analysis chart were compiled to analyze the sensitivity of gas content in coal seam.The sensitivity coefficients and critical points of each sensitive factor to gas content were calculated,and the critical point of sensitivity factors such as adsorption constant a and moisture were determined.
