摘　　要：在结点红外测温基础上应用改进谢别德插值法,并借助计算机软件对矸石山地表温度进行计算分析,得出地表高温区域分布;以煤矸石自燃标志性气体浓度为指标,利用多参数气体检测仪对地表高浓度区域进行判定;最后采用"先疏后密"的方式施工探测钻孔,逐步锁定矸石山内部火区,从而形成一套完善的矸石山自燃火区判定技术并应用于山西盂县玉泉煤矿。The improved Shepard interpolation method was used based on nodes infrared temperature measurement,and the computer software was adopted to calculate and analyze the surface temperature,then the distribution of land surface high- temperature area was obtained. The spontaneous combustion representative gas concentration was considered as the index to explore the land surface high concentration convergence area with the aid of multi- parameter gas detector. Finally the exploration drilling was arranged with the way of ＂ thick after sparse＂ to lock the internal fire area of gangue dump. Thus a set of improved spontaneous combustion area iudgment technology of gangue dump was developed and applied in Yuquan Coal Mine of Shanxi province.
