Pre-Cooling the Inlet Airflow of the Mine Utilizing the Shallow Rock Low Temperature Resource

Abstract:

In order to reduce operating temperature of deep mine, took shallow rock layer low temperature effect of mine as natural energy (cold) source in the spring and summer, used shallow abandoned waste roadway as cooling space to carry out research on deep cooling ventilation. Built model of heat and moisture exchange between inlet airflow and low temperature rock layer, carried out numerical simulation for inlet airflow cooling process of specific test mine. At the same time, inlet airflow cooling results of the experimental mine was gotten through testing and verifying. Results show: using this natural energy (cold)source that shallow rock layer low temperature effect of metal mine and abandoned resource of roadway, shaft, slop etc. cooling the inlet airflow instead of artificial refrigeration to auxiliary mine deep cooling in the spring and summer have practical saving energy significance and better applied prospect.
