Study on Application of Intelligent Decision Theory in Mine Ventilation System
Qingliang Wang · Safety in Coal Mines · 2007
Based on rough set and mathematic statistics theories,the state evaluation model for mine ventilation system is proposed.The ventilation index system is deduced by using heuristic algorithm on the basis of rough set theory.This paper uses the confidence interval analysis to evaluate the output of identification model.Then the evaluated results are feedback to modify the model.A closed-loop state evaluation model for ventilation is constructed based on intelligent decision theory.The practical case reveals that the model can increase the confidence and accuracy of evaluation.
