We introduce a novel horizontal-well hydraulic cavitation method to enhance extraction efficiency and mitigate outburst risks. This technology differs from traditional approaches by utilizing a mathematical model grounded in porous media theory and Darcy's law, accounting for hydraulic seepage and coal strength. Numerical simulations with COMSOL Multiphysics validated the model, identifying optimal construction parameters for hydraulic coal cutting. The proposed technology significantly advances safe and efficient coalbed methane recovery, benefiting coal mine safety and environmental sustainability.
