Evolutionary pattern and a calculation method of in situ gas pressure based on pressure-retaining coal cores

Evolutionary pattern and a calculation method of in situ gas pressure based on pressure-retaining coal cores

Objective and MethodsThe in situ gas pressure of coal seams represents a crucial parameter for the safe production of coal mines and the assessment of coalbed methane (CBM) resources. To overcome current limitations in determining the in situ gas pressure, such as prolonged measurement cycles and th...
