In China, soft coal seams make up over 50% of all coal seams. The instability and failure of boreholes in soft coal seams are key factors that result in an average gas drainage rate of less than 30% in China, which has become a “bottleneck” for safe and efficient coal mining. Based on 247 articles from the Web of Scien...

To address the low efficiency and uncontrollable fracture expansion in gas extraction from low-permeability hard coal seams, a synergistic permeability enhancement technology integrating loose blasting and hydraulic perforation (LBHP) is proposed. Combined with theoretical analysis, ANSYS/COMSOL numerical simulatio...

Coal seam gas drainage is crucial for reducing carbon emissions and ensuring safe coal mine production. In engineering, multiborehole combined drainage is widely adopted. However, the interaction among boreholes leads to the complex superposition of their respective influence zones. Previous research has largely focu...
