Influence of Pit Temperature on Air Leakage of the Overburden Layer from Open Pit to Underground Mining

摘要：

To mines turning from qpcn pit to underground mining with caving method as transition, air leakage of overburden layer in winter can lead to lower pit temperature, affecting their regular production. The paper is based on the theory of fluid flow in porous media, simulating wind velocity of overburden layer air leakage with FLUENT software and calculating influence of air leakage of the overburden layer on pit temperature under the condition of various porosities and thickness. The conclusion is drawn that overburden layer thickness is above 40m,air leakage influence on pit temperature is relatively little, thus offering scientific basis for rational overburden layer thickness and structure of open pit into underground mining.
