| 摘 要： | 通过对煤层瓦斯压力产生原因及瓦斯储层研究,确定了煤层中瓦斯压力(含残余瓦斯压力)与瓦斯含量(包括参与瓦斯含量)的关系,煤层保持完整或较完整状态时煤层瓦斯压力可以与瓦斯含量采用朗格缪尔方程互相反算,煤层处于破碎离散状态时,则煤层以块状呈现,煤层中存在瓦斯含量但相对瓦斯压力煤层瓦斯压力与瓦斯含量不适用朗格缪尔方程互相反算。

| Abstract: | The relationship between coal gas content and coal gas pressure was studied,based on the studied on coal gas pressure produce mechanics and the coal gas reservoir.The coal gas content and coal gas pressure can be calculated by Langmuir Equation,when the seam keeps full integrity.Otherwise,when the coal seam keeps the condition of dispersion and composes of massive,although it exists gas content in coal seam,the relation between coal gas content and coal gas pressure is not fit Langmuir Equation. |

| Keywords: | coal seam reservoir gas content gas pressure Langmuir Equation |
