摘　　要：矿井通风系统是一个开放系统,利用耗散结构理论,对通风系统的耗散条件和行为进行了研究,同时,用熵理论分析了矿井通风系统的不同演变状态,指出了决定矿井通风状态演变的4个熵阀值和2次突变,为矿井通风系统优化以及矿井通风安全管理提供了理论依据。Mine ventilation system is an open system. The dissipative condition and behavior of mine ventilation system were studied using the theory of dissipative structure. At the same time, the different evolution states of mine ventilation system were analyzed using entropy theory. The four entropic threshold values and the two mutations which determinate the evolution state of mine ventilation system were presented out. The study provided a theoretic basis for optimization and safety management of mine ventilation system.
