Study Of Design And Optimization Of Mine Ventilation Based On AutoCAD

Mine ventilation design is one of the main content of the design of mine,is the mainfactors which reflect the quality and level of design of mine.The paper done the research workof the following aspects for mine ventilation design,based on analyzed the existing ventilationsystem analysis method、aided design software、the present situation of the application ofCAD in mine ventilation design and the specific requirements of the design application andresearch development detailed:The paper analyzed the characteristics and influence factors of mine ventilation system,analyzed the application of ventilation analysis method like ventilation network sensitivity、stability、ventilation structures importance etc which previous studied in the ventilationdesign,optimized the selecting ventilation system design scheme and adjustmenting airvolume, provide further ventilation analysis tool for ventilation design.The paper analyzed the influence of traffic wind pressure caused by the tracklessrubber_tyred car to the wind nets,given the wind nets mathematic analytic type with trafficwind pressure through the analysis of influence of traffic wind pressure in a single and containthe tunnel branch,and then solutioned the analytical mathematics by the method ofScott-Hinsley； The paper comprehensive used commonly used adjust air methods toventilation CAD：use "fixed air volume method" to realize the on-demand points of the wind、use "access method" maximum resistance line、use "loop method" optimizing adjustmentbranch,peper only need to confirm with the wind point and the input with air volume in thesoftware system,it can be done directly mine air distribution and the formulation of regulationscheme through interactive operation,optimized the air volume distribution of mine wind nets.Finally the paper established the principle、platform、tool、database and index ofdevelopment of software system,and given the calculation process of the ventilation analysisfunction,developed mine ventilation aided design software, verified the practicality andaccuracy of software through the test,basis of the above study. The study perfecte suitable function of the mine ventilation aided designsoftware,improve the efficiency and quality of the design of mine ventilation.
