一、通风 (一)矿井采掘洞室风量计算方法波兰矿山救护总站目前主要是采用两种方法来计算矿井风量:其一是考察煤的瓦斯含量和井深条件,按吨煤所需风量计算,是估计矿井所需总风量的大概数值。其二是按矿井各采掘洞室及通风巷道等分别计算风量。即考虑瓦斯涌出量,参加井下生产最多人数,按每人每
I. Ventilation (i) Method for calculating air volume in mine digging tunnel Polish mine ambulance terminal currently mainly uses two methods to calculate the amount of mine air flow: The first is to inspect coal gas content and well depth conditions, and calculate the required air volume per ton of coal. Estimate the approximate amount of total air volume required for the mine. The second method is to calculate the air volume according to each of the excavation chambers and ventilation tunnels in the mine. That is, taking into account the amount of gas emission, the maximum number of people participating in underground production, per person per
