摘要
通过分析煤层瓦斯压力的影响因素,介绍了根据瓦斯压力梯度、瓦斯含量、残存瓦斯含量等间接测量瓦斯压力的方法及考虑地应力、地温影响的热力学理论和基于量纲分析的煤层瓦斯压力理论计算方法。
The indirect measurement methods and theoretical calculations were introduced based on analyzing the influence factors of coal seam gas pressure. The indirect measurement methods include using gas pressure gradient, gas content and residual gas content to predict the gas pressure. The theoretical calculation methods predict gas pressure with thermodynamic theory considering in-situ stress, formation temperature and dimensional theory.
