本文讨论了矿井通风系统分析的各因素,提出了判别风向稳定性的方法及判别式,风机稳定运转的条件式,及保证非常时期防止灾害扩大的基本条件。在满足通风系统安全稳定的基础上,又讨论了矿井通风系统的经济合理性,提出了主要扇风机动力消耗最低的必要条件以及局部调节措施优化的基本原则。并根据我国实际情况,提出各类矿井通风系统等积孔合理值的计算式及指标,它对矿井通风技术管理,有一定参考价值。 In this paper, the various factors of mine ventilation system are discussed, and the method of judging the wind direction stability and the discriminant, the condition formula of the steady operation of the wind turbine and the basic conditions for preventing the disaster from expanding during the abnormal period are put forward. On the basis of meeting the safety and stability of the ventilation system, the economic rationality of mine ventilation system is also discussed. The necessary conditions for the lowest power consumption of the main fans and the basic principle of local adjustment measures are proposed. According to the actual situation in our country, this paper puts forward the calculation formulas and indexes of the reasonable value of the accumulated holes such as the ventilation system of the mine, which is of certain reference value to the mine ventilation technology management.
