通过对矿井通风网络压能分布进行研究,建立了矿井通风网络压能分布的影响因素指标体系,对百米流程风阻、巷道阻力比、网络结构类型以及有无均压措施4因素进行了量化分析;提出了采用可变模糊理论评价分析矿井通风网络压能分布合理性的方法,并将该方法进行了实例应用,准确快速地找出了压力分布存在问题的巷道分支;应用表明:该方法可以较好地进行复杂矿井通风网络压能分布合理性评价,评价结果可为矿井通风网络数值模拟、矿井通风系统安全稳定性的评断提供依据。

Through the studying of pressure distribution of mine ventilation network,the factor index system of pressure distribution of mine ventilation network is established, and four factors of the hectometer wind resistance, the resistance ratio of the roadway, the types of network structure and applying voltage-sharing measures or not are quantitative analysed. The rationality evaluating method of pressure distribution of mine ventilation network is put forward based on the variable fuzzy theory,and this method is applied to the instance,the branch which pressure distribution is not reasonable is finded quickly and accurately. It shows that this method can evaluate the pressure distribution of complex mine ventilation network preferably,to provide the basis for numerical simulation of mine ventilation network and safety and stability evaluation of the mine ventilation system.
