Study on the change rule of airflow temperature field in ultra-deep mining shaft.

ABSTRACT: In the background of increasing depth of metal mining, the issue of airflow temperature field during the construction of ultra-deep shaft is very important, in view of the fact that there is still very little research related to this content at home and abroad, so this aspect of the research is very necessary in the process of the development of deep shaft mining. This paper focuses on the study of the patterns of change in the airflow temperature field during the construction of ultra-deep shaft, based on Newton's law of cooling and the first law of thermodynamics, and from the perspective of fluid dynamics, it puts forward a new theory - the theory of equilibrium enthalpy interface, which qualitatively and quantitatively derives the critical conditions of the three changes in the wind te
