在陕北神府矿区石窑店井田煤层自燃勘查中，依据勘查区地质特征，采取了“放射状”不规则网状高精度磁测扫面结合二维地震剖面相结合的综合物探方法，其中高精度磁测扫面确定自燃边界，二维地震剖面解释煤自燃层位。通过对两种物探勘查方法取得的资料进行分析、对比和综合研究，确定该井田2-2煤层存在自燃现象，并圈定了自燃边界。经钻孔验证，综合物探解释的边界和埋藏深度精度较高，其中埋深误差小于8.7m。该区的勘探结果表明采用高精度磁测和二维地震勘探相结合的物探方法，能够准确的圈定煤层自燃边界，为煤矿开发和采掘设计提供可靠的地质信息。

During the coal seam spontaneous combustion prospecting in the Shiyaodian minefield, Shenmu-Fugu mining area, northern Shaanxi, based on prospecting area geological characteristics, the integrated geophysical prospecting of combining“radial pattern”ir-regular netted high-precision magnetic coverage and 2D seismic section have been used. Of them, high-precision magnetic coverage defines spontaneous combustion limits and 2D seismic section interprets coal spontaneous combustion horizons. To use the data from the two methods carried out analyzing, contrasting and integrated study, have determined that the spontaneous combustion phenomenon does existed in coal seam No.2-2 in the minefield and delineated the limits of spontaneous combustion. After drilling verification, con-sidered that the spontaneous combustion limits and buried depth interpreted by the method have rather high accuracy, in which, buried depth error less than 8.7m. The prospecting results have demonstrated that the method can delineate coal spontaneous combustion lim-its correctly and can provide reliable geological information for coalmine exploitation, winning and opening designs.
