冲击破坏条件下煤的红外光谱特征研究
Study on Infrared Spectrum Characteristics of Coal Under Impact Damage
摘要
Abstract
We carry out quantitative and circular impact of coal samples from Datong Tashan Coal Mine through controlling the falling hammer impact system by electromagnetic,and the pulverized coal obtained after the impact failure is subjected to sample preparation and the analysis of infrared spectrum characteristics.The results show that the coal contains a large number of hydrogen bonds,and hydrogen bonds are broken during the impact process.The main property of Tashan coal is the hydroxyl self-association bond fracture.With the increase of impact strength,the hydrogen bond absorption intensity decreases.As the intensifying of coal destruction,the energy required for hydrogen bond fracture becomes larger and the decreased trend of hydrogen bond absorption intensity is greatly reduced,mainly presenting the non-linear characteristic.关键词
