Study And Application Of Refrigerating Capacity For Mine Production And Cooling System

This paper is based on the network solution of mine, classifying for different heat source. Inorder to determine the basic formula heat sources. Through of dividing different feature points ofmine, analyzing various types of tunnels, determining the calculation formula of thermal.Combined with the practice production of CHANG Chengwopu mine, Using calculation formulaof thermal, In order to get the romantic temperature parameters of coal mine, Providingtheoretical basis for the reconstruction of development system and the selection of ventilationsystem of high temperature mine. And underlying for next step of mine cooling.The change of temperature field is simulated by computer software in order to obtaindistribution of temperature field of tunnel in high temperature mine. This paper is applying CFDsoftware to simulate the temperature of face, with theoretical basis of numerical simulation,Airflow temperature distribution which is not set any cooling system in face is simulated.Through comparison simulation results with heat calculated results, Then it is proved thatnumerical simulation is correctness and feasibility. pipeline have been display installedposition installation.Separately from Refrigeration and cooling of Non Mechanical and Mechanical to makenumerically simulated, Air-Cooler and transport ice pipeline have been simulated, The result ofnumerically simulated display that the cooling effect of Air-Cooler is better than the transport icepipeline. Air-Cooler which is installed in different position is also numerically simulated, and thebest position of installation position is obtained by the result of numerically simulated.
