Development and prospect of mine ventilation technology and equipment

The paper introduced the latest achievements of mine ventilaion in ventilation theory ventilation systems venitiaton equipment and ventirition mornioring anayzed and summaized the progress of venilaion theor in venilato reliablitynetwork caculaton and catastrophe airfiow control. Meanmwiie,the new ideas of e ntilation system used incal mining face and heading face were intraduced. The aplicaion status of new equipment inluding the main fan.local fan and mine duct.the process status of ventilatio sensors,main fan monitoring and network mrntoring were analyzed.Fialy: n the basis of analizng the problems of urent mine ventiadion tech ology and equipmenthe author put onwar his own vie ws about the systen layout.equipment manufacturing level,monitoring technology and system disaster resistant ability of mine ventilation in the future,in order to provide a reference for the further development of the mine ventlation technology
