Experimental Study of Spontaneous Combustion Rule of Ground Coal Storage Pile

By field measurement and laboratory experiment, a yieldable thermometric instrument was studied and manufactured on the basis of the spontaneous combustion rule of ground coal storage pile The instrument has been applied to the ground coal storage pile in Meiyukou Coal Mine of Datong Bureau and the depths of its self-heating and combustion layers and the inherent property of its spontaneous combustion have been obtained.

地面储煤堆自燃规律的实验研究

通过现场实测和实验室试验，在分析地面储煤堆自燃规律的基础上，研制出可伸缩深基点测温仪表，并应用于大同矿务局煤峪口矿露天储煤场，得出煤堆自热层、自燃层深度值及煤峪口地面储煤堆自燃的内在特性。
