Research On Ventilation System Optimization And Transformation Based On "Ventilation Reliable" Policy In Tonghua Mining Industry (Group)

Jilin tonghua mining group is China’s large coal production base, there are five coal mine production,each mine all have different degree of the problem of ventilation and network complex. There is a great relationship between the mine ventilation system reasonable or not and mine safety production、the mine anti-disaster ability、the economic benefits of the mine and mine production sTab. and high yield. Due to the influence of mine ventilation system many factors, mine ventilation system optimization to a lot of mathematics calculation and the face of a complex mathematical model, so optimization work become very complex. In order to further implementation "take coal after gas,monitoring,with air volume sure production"gas control policy twelve words,structure "Ventilation reliable、Extraction standard、Monitor effective、 Administration in place"comprehensive management system of gas,solve the mine air volume insufficient,according to "Shorten the ventilation, Expand ventilation section, Process, Reduce air resistance increased ventilation ability, Improve anti-disaster ability" principle,Optimization of ventilation system, simplify the ventilation network,Do the wind flow sTab.ility,System reliable,Air volume enough,Wind speed of wind meets the requirement,according to5production of mine ventilation system for the actual research,after careful analysis,put forward the mine ventilation system optimization reform plan,in order to solve the solution accuracy ventilation network artificially low, the error, the problem of poor effectiveness,assure ventilated system optimization and transformation of scientific and advanced, applicability, etc.Through to the five production mines determination and a lot of air resistance ventilation data research,set up separately develop mine ventilation simulation system,For mine ventilation system reliability analysis, for mine ventilation system optimization and transformation of rationality study lays a foundation, make mine ventilation system optimization reform plan。...
