    Evolutionary pattern and a calculation method of in situ gas pressure based on pressure-retaining coal cores by Mingzhong GAO, Jie SONG, Pengfei CUI, Yongcheng LI, Zhipeng WANG, Xuemin ZHOU, Ju LI, Zongxin HAO, Haichun HAO

    Published 2025-04-01
    “…Results and ConclusionsThe results indicate that: (1) Influenced by high gas pressure, the gas pressure within the pressure-preserved space more easily reaches a new equilibrium. During the isothermal adsorption process, the gas pressure exhibits a staged evolution characteristic, where the gas pressure in the pressure-preserved coal core first rapidly decreases to a certain value, then increases before gradually stabilizing. (2) Due to the pore characteristics of the coal sample being dominated by mesopores and having a large micropore volume, the higher the moisture content of coal leads to greater resistance to gas adsorption, resulting the longer the equilibrium time and the lower the adsorption pressure drop. (3) The gas pressure of the coal samples was calculated based on the expansion desorption experiments of pressure-preserved coal cores with different moisture contents. …”
