| 摘 要： | 首先确定了孔壁周围瓦斯的流动模型及瓦斯压力表达式，进而根据瓦斯含量与瓦斯压力的关系，推导出了瓦斯损失量的理论计算公式，最后提出了瓦斯压力的修正方法.从实际应用来看，修正后的瓦斯压力要高出实测压力几个百分点，采用胶囊黏液封孔所测的瓦斯压力相对误差较小.

| Abstract: | The fluxion model of gas and the gas pressure formula were decided in the surrounding of bore wall firstly,and according to the relation of gas content and gas pressure,the theory calculation formula of gas loss quantity was deduced,and finally,the revision method of original coal gas pressure was brought.According to the application results actually,the original coal gas pressure revised is a few percents more than the actual measuring pressure,and relative error of gas pressure that the bore is sealed by making use of capsule-mucus is smaller. |
