采用多台通风机分区并联通风,可以合理增加矿井的需风量。矿井等积孔是评价矿井通风易难程度的一项重要指标,但并不能准确、全面地反映其真实易难、好坏程度,尤其是在多风井多风机并联通风当中,全面进行矿井通风可靠性评价,要考虑主要通风机的运行工况、供风量、矿井瓦斯涌出量、采煤方法和开采强度等因素,以保证通风系统的合理、稳定、可靠。文章分析了多风机分区通风并联运转的相互影响以及多风井多风机通风方式通风难易程度的评估。
The use of multiple ventilators partition ventilation in parallel, can reasonably increase the amount of air required by the mine. Mines and other accumulation of holes is to assess the degree of mine ventilation is an important indicator of ease, but does not accurately and fully reflect the real difficulties, good and bad, especially in the multi-wind multi-fan ventilation in parallel, the full mine Ventilation reliability assessment, to consider the main fan operating conditions, air supply, mine gas emission, mining methods and mining strength and other factors to ensure the ventilation system is reasonable, stable and reliable. The paper analyzes the interaction between multi-fan ventilation and parallel operation and the assessment of the ventilation difficulty of multi-fan ventilation.
