Efficient gas extraction technology via surface wells in goaf areas of deep outburst-prone coal mines
Published 2025-06-01“…Regarding the impact of mining-induced strata movement on the well structure, a three-stage directional well structure was adopted, optimizing the three-stage drill sections to match the casing, enhancing the well’s resistance to strata shear damage, and ensuring the stability of surface wells under complex geological conditions. Combining the "O"-shaped fracture distribution theory, numerical simulation of gas seepage distribution, and the calculation of the "three zones" distribution theory, surface wells were arranged 20 m away from the high-extraction roadway, with the well end located within a 30 m fracture zone above the roof of the working face, ensuring high efficiency of gas extraction. …”
