Research On Optimization Of Underground Ventilation System In Lukuishan Iron Mine

Mine underground ventilation system,as one of the most important auxiliary systems in mine mining production activities,is accompanied by continuous changes in the depth of mining activities,output,and mining area layout.Therefore,when the mine ventilation system cannot meet the needs of mine production,it should be optimized in time to meet the needs of mine production.This article is based on the research of the "Underground Ventilation System Rectification Investigation of Lukuishan Iron Mine",and conducts in-depth research on the problems of insufficient air intake,air leakage,and dirty air circulation in the underground ventilat ion system of Lukuishan Iron Mine in Xinping County,Yunnan Province:1.Read and read the theoretical research and engineering example processing done by domestic and foreign scholars on the optimization of the mine ventilation system,and find methods and ideas for the optimization and reconstruction of the ventilation system.2.Through the research on the optimization technology of mine ventilation system,it explains how to analyze the abstract mine ventilation system into a mathematical model through graph theory,and analyzes the three basic laws of wind flow by using mathematical model The theory of Hardy-cross iterative method was combed,and then the theory of optimal ventilation system scheme was studied.3.In-depth investigation of the current s ituation of the mine ventilation system,parameter measurement,and calculation of the total air volume in the Lukuishan Iron Mine to find out the problems Mine ventilation calculation software draws a three-dimensional diagram of the ventilation system of three schemes,respectively solves the ventilation network of the three schemes,analyzes the results based on the calculation of the Ventsim ventilation software,and conducts preliminary selection of the three schemes.4.Finally,establish the evaluation index system of the ventilation system,and combine the analytic hierarchy process,fuzzy mathematics theory,and gray correlation theory to establish the gray comprehensive fuzzy comprehensive evaluation model of multi-objective decision-making.After optimizing,the optimal scheme suitable for the underground ventilation system of Lukuishan Iron Mine is finally obtained.
