The Program Design And Application Research Of Sensitivity Calculation And Diagonal Branch In Mine Ventilation System

This paper was subsidized by National Natural Science Foundation"Theventilation system reliability,stability,security theoretical studies(50704019)",and thispaper is the subject of some research results．Diagonal branch is benefit for cowl mineventilation system．Orders for the diagonal branch of research is to stay in the definitionof the mine ventilation network．In this paper,a broad definition of diagonal branchgives the diagonal branch automatic identification method,and the algorithm and thepartical application was given．In this paper,mine ventilation system sensitivity'S caculation is put forwardinnovative and be applied to the actual site．Also completed the mine ventilation systemsensitivity calculation program,and combined with the actual application analysis．Thedifferent between sensitivity of theoretical calculations and the actual calculation werefounded and putted forward a new method to determine sensitivity of convergence．Putforward the concept of convergence factors and using experimental methods to solve thedifferential sensitivity of the numerical calculation of the optimal step length,SO as tosolve the error problem．...
