中文摘要：
根据矿井通风网络风流按需分配的要求，应用和声搜索算法对矿井通风系统网络的非线性规划数学模型进行优化计算，采用罚函数法对约束方程及限制条件进行转化和处理，改进的和声搜索算法克服了传统的通风网络优化控制算法的某些局限性；通过对示例通风网络的优化模型进行求解，仿真结果显示，优化后单风机通风网络总能耗降低了3225W，其下降幅度约为3．81％，多风机通风网络总能耗降低了17779W，其下降幅度约为6．76％，改进后的和声搜索算法可以很快收敛于最优值，取得了不错的优化效果。
英文摘要：
Based on the air distribution request of the mine ventilation network, carries on the optimized computation to the mine ventilation system networks nonlinear programming mathematical model using harmony search, uses penalty functions method carries on the transformation to the constraint equation and the limiting condition, the improved harmony search has overcome certain limitations of the tradition- al ventilation network optimization control algorithm. Through solving the optimized model of the ventilation network, the simulation result shows that the overall energy consumption of the optimized single--fan ventilation system has a decrease of 3225W, with a decreasing rate of 3. 81%, and the overall energy consumption of the optimized multiple--fan ventilation system has a decrease of 17779W, with a decreasing rate of 6.76%, the improved harmony search algorithm may converge to the optimum value quickly, has obtained the good optimized result.
