Analysis of Coal-Rock's Cutting Characteristics and Flash Temperature for Peak Based on Infrared Thermal Image Testing
摘要
Abstract
In order to realize the accurate dynamic identification of coal-rock interface during the cutting process of shearer,studied on the infrared thermal image characteristics and the transient flash temperature difference of shearer in the process of cutting coal and rock,established the coal-rock cutting testing bench for shearer's picks, obtained the temperature evolutionary law and flash temperature characteristic by analyzing. The study indicated that both producing the unexpected point flash temperature region at the tip of the pick during cutting coal and rock , and the range of flash temperature zones and the transient peak is significantly larger than that of coal cutting pro-cess,the difference of peak value varies inversely with the haulage speed and drum speed of shearer,and the great-er the hardness difference of coal and rock is,the more obvious the difference of picks'temperature field peaks will be. The research results provide important theoretical and numerical basis for the dynamic identification of coal-rock interface.关键词
