A probe into mine cooling technology

摘要

The temperature in an underground mine rises with the increase of mine depth.Mine thermal harm has become the fifth largest disaster for coal mine production, which jeopardizes workers' health and safe production of coal mines.This thesis analyzes the causes of mine thermal harm and summarizes the non-artificial refrigerating measures currently applied for mine cooling.This thesis mainly introduces the working principles of refrigerating station in artificial cooling system as well as issues about heat exchange, cooling convey and condensing heat discharge in air coolers, and briefly analyzes the different settings of refrigerating station system and their respective advantages and disadvantages.
