摘要
根据煤层自燃后底顶板岩石的热剩磁而产生的这一定强度磁异常特征,通过地面高精度磁测工作,并对地面磁异常剖面进行反演,同时结合地质、露头调查等资料综合分析,达到圈定煤层自燃边界的目的。
According to the spontaneous combustion of coal seam of bottom roof rock after thermoremanenee and produce the magnetic anomaly t＇haracteristics of a certain intensity, through the ground high-precision magnetic measurement work, and on the inversion of the ground magnetic anomaly profile,at the same time, combined with the comprehensive arlalysis of geolngical outcrop survey data,to delineate the purpose for the boundaries of coal seam spontaneous combustion.
