一、综合指标综合评述地下矿山通风系统优劣的问题,是矿业技术经济分析中的一个重要课题,它不但直接关系到井下职工的健康和安全,同时对劳动生产率和开采的经济效果也有着重大的影响。对于这个问题,以往提出过一系列指标,诸如等积孔、扇风机效率、扇风机装置效率、有效风量率、漏风率、获风率、风质合格率、单位矿石产量电耗等等。这些指标 I. Comprehensive Index A comprehensive review of the pros and cons of underground mine ventilation systems is an important issue in the technical and economic analysis of mining. It not only has a direct bearing on the health and safety of underground workers, but also on the productivity of labor and the economic effects of mining Impact. For this problem, a series of indicators have been proposed in the past, such as equal hole, fan efficiency, fan fan device efficiency, effective air flow rate, air leakage rate, wind yield, wind qualified rate, power consumption per unit of ore and so on. These indicators
