不同含水率对磷块岩热红外辐射特征的影响研究
Study on the influence of different water content on thermal infrared radiation characteristics of phosphorus block rock
摘要
Abstract
In order to explore thermal infrared radiation characteristics of phosphorite with different water content,uniaxial loading tests were carried out on dried phosphorite,natural water-bearing phosphorite and water-saturated phosphorite respectively,and the mechanical characteristics,failure characteristics and infrared radiation characteris-tics of phosphorite with different water content were analyzed.The results show that the higher the water content of phosphorite,the larger the temperature rise amplitude of infrared radiation before instability,the lower the water con-tent and the smaller the temperature rise amplitude;the infrared precursor anomaly of phosphorite shows that a short temperature drop phenomenon will occur before fracture,the higher the water content,the smaller the temperature drop amplitude,the lower the water content and the larger the temperature drop amplitude;the infrared radiation temperature rise will occur at the moment of final fracture of phosphorite,the lower the water content,the larger the abrupt change value,the higher the water content and the smaller the abrupt change value.关键词
