Optimization of Ventilation System Using Ventilation Network Analysis

摘要

This paper discusses a new method for optimization of mine ventilation system. The method is based on criteria as follows: (1) minimize the size of each regulator; (2) minimize the number of regulators; and (3) minimize the total power consumption of fans. Based on this theory, the optimization problem of the ventilation system is classified as optimization of mine ventilation network and calculation of operating points of fans. Furthermore an algorithm that determines the economical operating point of fans while calculating the optimum controls of ventilation network is proposed. The main features of this method are that it does not require the analysis of a large-scale nonlinear programming problem, and the optimal solution can be obtained by means of existing programs for mine ventilation network analysis.
