China is a country with coal as the main energy production and consumption.Coal consumption accounts for over70%of primary energy consumption, coal is inour country national economic development pillar. Mine ventilation and safety,efficient production of the coal mine can guarantee. In recent years, along with thecoal mine mechanization level rise ceaselessly, the tunneling working surface lengthincreases, driving speed, single lane tunneling ventilation difficulty on technology andmanagement also is increasing ceaselessly. HuHeWuSu coal mine4103working faceexcavation trough reaches2000m, along with the tunneling length increases, theventilation problems have become increasingly prominent. Therefore, HuHeWuSucoal mine in4103heading face local ventilation technology optimization, establishinga safe and reliable, reasonable economy, convenient management of ventilationsystem, to ensure the safety in production of high efficiency has the importantpractical significance.This paper briefly introduced the domestic long distance local ventilationtechnology, the intelligent local ventilation technology and other aspects of thedevelopment of. Subject of the HuHeWuSu coal mine the basic situation, the mainproblem for ventilation, the use of domestic and foreign mature and advancedventilation technology to solve the HuHeWuSu coal mine ventilation problems. Theprimary content of the subject is the selection of appropriate local ventilation deviceincludes big power local ventilator and the large diameter cylinder; double laneparallel tunneling, total pressure and the local ventilation combining intelligent localventilation technology; the right of the anchor net support; shotcrete closed tunnel;and a gas concentration monitoring. Improve the security system, reasonable to thetunneling working surface with the wind, gas emission,make the supply of air toprotect the safety of operating personnel working at the same time can turn the gasconcentration dilution to safe concentration following, to create a good workingenvironment, feasible in technology, reasonable in economy under the premise,achieve the safety purpose driving long lane the high yield and high efficiency mine,to provide protection.Optimized ventilation system effectively improves the HuHeWuSu coal mineventilation effect, shorten the length of single lane air supply, improve the effective airvolume rate, achieve the purpose of safe driving. A single from the fan energy consu- mption each year for the HuHeWuSu coal saving of460000yuan. The long lanetunneling aeration technology applied in the call and the Ukrainian coal mine,achieved good results. This technique has certain promotion value.
