用矿井通风等积孔的大小来表达矿井通风的难易程度,其由来已久,得到了普及,但是在现行条件下应如何进行分级,并以此来改善煤矿通风,提高矿井生产的安全性与经济效益,这是值得商榷的。本论文对中国141个煤矿矿井的通风等积孔与矿井风量的关系进行了回归分析,探讨了产生这种相关关系的原因,在此基础上,根据煤矿设计规范和广泛使用的扇风机性能,提出了新的划分矿井通风难易程度的分级方法,这个分级方法对矿井通风设计、通风技术管理以及通风改造工程有很大意义。
It is a long time and popular way to express the difficulty of mine ventilation by the size of the hole such as mine ventilation. However, how to classify under the current conditions to improve the ventilation of coal mine and improve the safety of mine production? And economic benefits, it is debatable. In this paper, the regression analysis of the relationship between the ventilation holes and the air volume of coal mines in 141 coal mines in China is carried out. The reasons for this correlation are discussed. Based on the coal mines design specifications and the widely used fan performance, Proposed a new classification method to classify the degree of difficulty of mine ventilation. This classification method is of great significance to mine ventilation design, ventilation technology management and ventilation renovation project.
