矿井风量调节是矿井通风技术管理的一项重要工作,也是矿井通风设计的内容之一。风量调节工作的好坏,对于煤矿安全生产、降低通风动力费和提高矿井经济效益均有重要意义。近几年来,由于老井改、扩建和新的大型、特大型矿井的投产,矿井复杂通风网路的风量调节已成为普遍现象。但是,如何获得复杂通风网路的最佳调风方案,却是一个值得研究的问题。众所周知,风量调节方法是多种多样的,对于局部地区的风量调节,由于增阻法施工和管理技术简单、投 Mine air volume regulation is an important work of mine ventilation technology management, and it is also one of the contents of mine ventilation design. Air quality regulation work is good or bad, for coal mine safety production, reduce ventilation costs and improve mine economic benefits are of great significance. In recent years, due to the alteration of old wells, expansion and the commissioning of new large and extra-large mines, air volume regulation of mine complex ventilation networks has become a common phenomenon. However, how to get the best ventilation scheme for complex ventilation networks is a problem worth studying. As we all know, air volume control methods are varied, for some areas of the air volume adjustment, due to resistance increase method of construction and management of simple investment
