4. Results and Discussion This section first optimizes the system under a certain heat transfer rate and verifies the accuracy of the method through experiments. Then, the adaptability of the optimization method under different operating conditions is discussed. 4.1. Optimization Results and Experimental Verification Table 8 shows the initial temperature boundary values.
Abstract : Significant harm from heat has become a key restriction for deep metal mining with increasing mining depth. This paper proposes a refrigeration ventilation system for deep metal mines combined with an existing air cycling system and builds an experimental platform with six stope simulation boxes. Using the heat current method and the driving-resistance balance relationship, the heat transfer and flow constraints of the system were constructed.
