目前,判断通风状况的指标已有很多,如矿井总供(包括总进与总回)风量,应进风量比、负压水柱、等积孔、有效风量率等。这些指标都能从不同侧面表明矿井通风状态的好坏,是些很有用也很重要的数值指标,这一点已为大家所公认。通过我们近年来的实践,感到除现用指标外,似乎还需要再有一个“风量分配合理性”方面的指标,下面谈谈个人的一些看法。
At present, there are many indicators for judging the ventilation status, such as total gas supply (including total gas input and total gas supply), air-to-air ratio, negative pressure water column, equivalent hole, and effective air flow rate. These indicators are from different sides of the mine ventilation state is good or bad, is a very useful and important numerical indicators, it has been recognized by all. Through our practice in recent years, I feel that besides the current indicators, there seems to be another indicator of the rationality of air volume allocation. Let’s talk about some personal opinions.
