摘要
针对煤层自燃区自燃边界确定问题,通过对比分析陕北某地实测地面高精度磁场特征与钻孔勘探结果,认为采用ΔT垂向一阶导数方法能够有效地圈定煤层自燃边界。
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 AT vertical first derivative method can effectively delineate the self-combustion boundary of the coal seam.
