| Abstract: | Aimed at determining the boundary of the coal seam self-combustion area, the authors made a comparative analysis of surveyed ground high-precision magnetic field characteristics and drilling results. On such a basis, it is held that the adoption of ΔT vertical first derivative method can effectively delineate the self-combustion boundary of the coal seam. |
