Research Of Optimization And Alternation To Tong Hua Mining Co., Ltd's Ventilation System

This paper is aimed at ventilation system problems of the Tong Hua Mining Co., Ltd; using advanced computer technology combined the production palnning of company to improve the mine ventilation system. It achieved the object of ventilation reliable, production quotas depend on wind and laid a solid foundation for the company's next goals by leaps and bounds. In this paper, we deathly studies the theory of mine ventilation simulation and the mathematical model of algorithms first, then according to actual needs, conducting a systematic survey of mine belongs to this company, creating mine ventilation simulation system and using the mine ventilation simulation system to simulate the ventilation program and improve the mine ventilation systems. In one hand this paper use the mine ventilation simulation system to analyse and evaluate the reliability of the mine ventilation system, to study the rationality of the mine ventilation system structure for the Tong Hua Mining Co., Ltd on the other hand, according to the status of ventilation shaft ,aiming at the demand of the ventilation improvement and expansion reconstructe, combining the mine ventilation simulation system, we make several project of the Tong Hua Mining Co., Ltd. (1)The airflow adjustment project, 1.8 million tons expansion project for the Babao mine. (2)the 1.2million and 1.5 million tons ventilation system improvement project for Pine tree mine (3)the ventilation system for the demand of the wind by the Yongan mine late era. (4) the windwell sinking simulation project, the fan selection simulation project, 1.2 million tons improvement simulation project for the Liudao river mine of Yongan mining co.Ltd (5) the simulation project for transition period and expansion project for late period for Daoqing mine. Through the effort of the two years,The Tong Hua Mining Co., Ltd using the mine ventilation simulation system to made improvement proposal for the ventilation system, on the condition of ventilation reliable, increase the production of the mine. The ventilation ability of the mine has reach the 7.59 million tons per year from 4.66 million tons per year , acquired good benefit economic benefits and social benefit,making the positive effect for the safe production in Tong Hua Mining Co., Ltd...
