摘　　要：为了有效探测煤矸石场自燃高温区的分布范围及发展趋势,利用综合探测方法进行自燃高温区识别,首先采用覆盖层介质内部直接测温方法确定温度场平面分布范围,然后利用高密度电法探测自燃区的延伸范围和深度,最后采用钻孔测温方法验证自燃区位置和范围的准确性。结果表明,该综合探测方法对确定煤矸石场自燃高温区的平面和深度延展情况是切实可行的,可为煤矿矸石场高温区探测提供新的思路。In order to effectively detect the distribution range and development trend of spontaneous combustion high temperature area of coal gangue yard.A comprehensive detection method is used to identify the high temperature zone of spontaneous combustion.First,the direct temperature measurement method inside the covering medium is used to determine the plane distribution range of the temperature field;then,the extended range and depth of the spontaneous combustion zone is detected by high-density electrical method;finally,the accuracy of the location and range of the spontaneous combustion zone is verified by drilling temperature measurement method.The results show that the comprehensive detection method is feasible to determine the plane and depth extension of the high temperature area of spontaneous combustion in coal gangue yard,and can provide a new idea for the detection of high temperature area of coal gangue yard.
