Study and application of the influence of inclination angle on the cross-fusion mechanism of high gas thick coal seam

• The boundary of the gas transport zone is located in the region of fracture separation, while the gas storage area boundary is in the abrupt penetration zone. • Fracture rate and fracture entropy, based on information theory, determine the state of gas transport and storage areas. • A mathematical model representing the dip effect on gas transport and storage areas was established, providing criteria for regional location. • The cross-fusion evolution process of the dip effect was revealed, offering guidance for directional and accurate gas extraction.
