Distribution of Roadway Resistance in Hudi Coalmine Ventilation System Based on Fuzzy Comprehensive Evaluation

针对复杂矿井通风系统阻力分布评价方法单一、人工经验依赖度较高的问题,在矿井通风参数测定及网络解算的基础上,从通风网络结构、通风巷道类型、巷道物理参数、巷道通风参数四方面,建立了影响矿井通风阻力分布的影响因素指标体系,提出了矿井通风阻力分布模糊综合评价方法。在胡底矿应用结果表明,该方法可以快速计算通风网络各巷道的可调节度,确定通风网络中的关键可优化调节巷道,为通风系统优化管理提供依据。

The resistance distribution of the complex mine ventilation system has the problems of single evaluation method and high dependence on manual experience. Based on this, on the basis of the measurement and network calculation of mine ventilation parameters, the index system of influencing factors on the distribution of mine ventilation resistance was established from four aspects: the structure of ventilation network, the type of ventilation roadway, the physical parameters of roadway and the ventilation parameters of roadway, and a fuzzy comprehensive evaluation method for the distribution of mine ventilation resistance was proposed. The application results of Hudi mine show that the method can quickly calculate the adjustable degree of each roadway in the ventilation network, determine the key optimized regulating roadway in the ventilation network, and provide a basis for the optimization management of the ventilation system.
