矿井有效风量率是评价通风系统的一个主要技术指标,通过测定计算来发现通风系统上存在的问题和采取相应的措施,保证工作面排除粉尘和有毒有害气体所必需的风速和风量,不断改善劳动条件。因此要求有效风量率这个指标必须目的明确、概念清楚,起到便于测定、指导措施的作用。根据几年来的实践,我们认为把有效风量率这个指标,作为检查矿井风量的利用程度或漏风程度是合理的,两者之间必须符合下列关系:
The effective air volume rate of mines is a major technical index for evaluating ventilation systems. The problems existing in the ventilation system and the corresponding measures are found through the measurement and calculation, and the necessary wind speed and air volume to eliminate the dust and toxic and harmful gases on the working face are ensured. condition. Therefore, the effective air volume rate required for this indicator must be clear, the concept clearly, play a role in measurement and guidance measures. Based on years of practice, we consider it reasonable to use the indicator of effective air volume rate as a measure of mine air volume utilization or air leakage, and the following relationship must be observed between the two:
