在矿井风量计算的现用方法中,有一种是按井下同时工作的最多人数来计算。虽然这种方法已经使用很久了,但理论依据是什么?仍可议论一下,以便人们做出合适的评价。这种方法用下式计算矿井的总风量 Q:Q=4NK 米~3/分……………(1)式中:N——井下同时工作的最多人数,人;K——风量的备用系数,它是矿井瓦斯涌出不均衡系数、矿井内部漏风系数、……等的总概括;4——以人数为计算单位的供风标准,即按井下每人每分钟4米~3的单
One of the current methods of calculating mine volume is to calculate the maximum number of persons working in the well at the same time. Although this method has been used for a long time, what is the rationale? It is still arguable that people should make a proper assessment. This method uses the following formula to calculate the total air volume of the mine Q: Q = 4NK m ~ 3 / min ............... (1) Where: N - the maximum number of people working underground at the same time, K; Coefficient, which is the inequality of mine gas emission coefficient, the mine internal air leakage coefficient, ... and so the general summary; 4 - the number of units for the supply of wind standards, that is, downhole per person per minute 4 to 3 single
