摘要
煤层瓦斯压力是矿井瓦斯基本参数之一,它反映了煤层中瓦斯的赋存状态,是判断煤层突出危险性的重要指标,同时也是采取抽放措施的重要参考依据,因此准确地获取煤层瓦斯压力是非常重要的。本文基于瓦斯地质理论,以影响煤层瓦斯压力的地质构造因素为出发点,应用量纲分析方法,建立了煤层瓦斯压力的数学计算模型,并通过实例计算了某矿井煤层的瓦斯压力,从而验证了该计算模型能够较准确地反映实测结果。
Coal seam gas pressure is one of the basic parameters of mine gas,for it reflects the condition of gas in coal and it is a significant index to judge the risk of coal and gas outburst.Simultaneously,it is the important reference on the drainage measures.Therefore,it is very important to acquire the coal seam gas pressure accurately.Based on the gas geological theory and beginning with the geological structure factors that influence coal seam gas pressure,the calculation model of coal seam gas pressure is established with the application of dimensional analysis method.The comparison analysis of field measurement and theoretical calculation shows that the calculation method based on the dimensional theory can more accurately reflect the measured results.
