摘要
根据青龙同昌煤业15煤层实测瓦斯含量值和对青龙同昌井田构造特征分析,结果表明煤层埋深是影响15号煤层瓦斯赋存的主要控制因素。15煤层瓦斯含量梯度为0.0051m3/(t·m),瓦斯压力梯度为0.0007MPa/m,瓦斯含量和压力整体上呈现"中部大,东西两翼小"的规律。
According to the measurement of gas content and the tectonic characteristics of Tongchang coal feld, the results show that the burial depth of coal seam is the main controlling factor for the occurrence of gas in 15 coal seam. 15 coal seam gas content gradient is 0.0051m3 / （t·m）, the gas pressure gradient 0.0007MPa /m, the gas content and pressure as a whole show ＂the middle is large, east and west wings small＂ rule.
