煤矿掘进工作面瓦斯涌出规律

Law of Gas Emission in Driving Face of Coal Mine

为了研究掘进工作面落煤瓦斯涌出规律,确定瓦斯灾害治理与采区通风合理设计,通过解吸法测定掘进工作面落煤瓦斯含量,探讨落煤瓦斯解吸量与暴露时间二者的关联性,由此建立数学模型。研究表明,瓦斯解吸量与暴露时间二者呈反相关性,表现出似双曲线变化特征,由此建立掘进工作面瓦斯涌出规律预测模型,该研究对掘进工作面瓦斯管理具有重要借鉴意义。

To study the law of coal gas emission from driving face and determine the reasonable design of gas disaster control and ventilation in mining area,the coal gas content of driving face is determined by desorption method,and the correlation between coal gas desorption and exposure time is discussed.The mathematical model is established.The results show that the gas desorption and exposure time are inversely correlated,showing hyperbolic variation characteristics,based on this,the prediction model of gas emission law of driving face is established.This study has important reference significance for gas management of driving face.
