预制裂纹煤样受载破坏的红外辐射特征研究
Research on infrared radiation characteristics of pre-cracked coal sample under loaded breaking
摘要
Abstract
Uniaxial compression test was conducted on pre-cracked coal sample,and infrared radiation temperature and its change rule of the pre-cracked coal sample under loaded breaking were researched.The experimental results show that infrared radiation temperature curve will mutate in process of loaded breaking of the pre-cracked coal sample,and the infrared radiation temperatures of the pre-cracked coal samples with different angles will suddenly increase during main rupture.The mutation rate of infrared radiation temperature increases first and then decreases with increase of pre-cracked angle during main rupture,and the mutation rate of infrared radiation temperature of the pre-cracked coal sample with 45° is the largest.The change rule of infrared radiation of the pre-cracked coal sample is closely related to load and pre-crack,which can reflect internal rupture of macroscopic defective coal sample under load.关键词
