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 selfcombustion area, the authors made a comparative analysis of
surveyed ground highprecision 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 selfcombustion boundary of the coal seam.
