摘　　要：结合煤层的赋存特点,首次将油、气田开发过程中压力恢复曲线的成熟理论和基本公式应用到露天煤矿煤层瓦斯赋存参数测定中,构建用于煤层瓦斯赋存参数测定的压力恢复曲线理论和方法,并在和顺吕鑫煤矿进行了验证试验,试验表明压力恢复曲线可以真实准确反映出煤层瓦斯参数的情况。Combining with the occurrence characteristics of coal seam, the article applies the mature theory of pressure recovery curve and the basic formula to the determination of coal seam gas occurrence parameters for the first time in the process of oil and gas field development. The mine builds the theory and method of pressure recovery curve for the determination of parameters,which is verified by Lvxin coal mine. The test shows that pressure recovery curve can accurately reflect the real gas parameters of coal seam.

关 键 词：压力恢复曲线 露天煤矿 瓦斯参数
