[Abstract]:The optimization of mine ventilation system is a complex decision problem composed of quantitative and qualitative interrelation, mutual influence and mutual restriction. On the basis of consulting and referring to a large number of documents, this paper analyzes the relevant data of 13-8# orebody group in Yunxi Laochang Tin Mine, and obtains the basic data of ventilation system of 13-8# Ore body Group. According to the development system and mining method of 13-8# orebody group, the ventilation system is constructed. According to the characteristics of the ventilation system of 13-8# orebody group, several different ventilation system schemes are worked out. 3Dvent ventilation software is used to calculate and analyze each scheme. According to the evaluation index system established in this paper, The relative binary comparison method in fuzzy mathematics and the grey relational projection theory of multi-objective decision-making are used to optimize the selection of each scheme and to determine the optimal ventilation system scheme. In this paper, the optimization scheme of ventilation system of 13-8# orebody group is selected, and the optimization of ventilation system is realized. The research results have theoretical significance for practical production. The main results and conclusions of this paper are as follows:. This paper expounds the optimization design of mine ventilation system and its application research. According to the present production situation of 13-8# orebody group, the scheme of mine ventilation optimization system is drawn up, and the network calculation is carried out, and the optimal scheme is finally determined. 2) through the analysis of the development map, geological characteristics and existing ventilation system of the 13-8# orebody group, the problems existing in the ventilation system of Laochang Mine are expounded, and the purpose of optimizing the ventilation system of the 13-8# Ore body Group is put forward. According to the design principles and practical requirements of mine ventilation system, a feasible scheme to meet the actual mine ventilation needs is drawn up after careful analysis and study. (4) drawing ventilation network diagram by using ventilation calculation software 3Dvent mining software, and calculating the draft plan of mine ventilation system, analyzing the result of calculation, and understanding the specific distribution of air volume and pressure distribution of mine ventilation system. Optimal selection of fans and design of a reasonable and reliable ventilation system. 5) according to the actual situation and theoretical knowledge of 13-8# orebody group, the evaluation index system is constructed, and the weight of each evaluation index is assigned by AHP. The grey relational projection method of multi-objective decision making is used to optimize the evaluation of each scheme. The essence of the grey relational projection method of multi-objective decision making is to determine the index data of the optimal and ideal scheme according to the size of the index data of each scheme. The relational degree judgment matrix is constructed, the projection value of each scheme is determined, and the optimal scheme is determined according to the size of the projection value. Based on the actual situation of ventilation system of old plant and 13-8# orebody group, the optimization design of ventilation system of 13-8# orebody group is realized through the optimization of ventilation system scheme, which has certain theoretical guiding significance and practical value.
