Description
Zhihua Yan and colleagues published a 2026 study on extracting methane gas from coal seams that have been squeezed and deformed by geology, using hydraulic fracturing. Gas output depends on how water pressure, rock mechanics, and fracturing damage interact. The team built a coupled simulation to untangle those effects and to test prediction models.
In the simulations, the coal's starting permeability and the rate at which fracturing fluid was pumped had strong positive effects on gas output, while stiffer coal reduced it. Damage area and peak permeability after fracturing were tracked alongside output. Three machine learning models were compared for predicting production. The work aims to help engineers choose fracturing settings for difficult coal seams.
