A Novel Gas Extraction Technique in Coal Seams Utilizing Hydraulic Fracturing‐Dissolution and Analysis of Non‐Uniform Propagation of Fracture

Energy Science &Engineering, Volume 13, Issue 6, Page 2842-2855, June 2025.
ABSTRACT Extracting gas from low‐permeability coal seams is essential for mine safety and efficiency. To address this challenge, a novel technique combining hydraulic fracturing and dissolution was proposed. The feasibility of this method was verified through simulations based on the distinct element method.
