阳煤五矿通风系统优化改造研究

Research on the Optimization and Transformation of Ventilation System in No.5 Coal Mine of Yangquan Coal Industry Group

矿井通风系统担负为矿井持续供给新鲜空气、排出各类气体的重任。随着矿井开采深度和强度的增加,地质条件越加复杂,通风系统的优化改造成为重中之重。阳煤五矿原矿井通风方式为机械抽出式,采用中央并列式通风,回风井为回风斜井,它们共同担负通风任务。经验算,通风系统已无法满足矿井整合后的通风要求,需对矿井主通风设备进行升级,同时对各采区通风系统进行验算优化。

The mine ventilation system is responsible for the continuous supply of fresh air and the discharge of various gases.With the increase of mining depth and intensity,the geological conditions become more complex,and the optimization of ventilation system becomes the most important.The original ventilation mode of No.5 Coal Mine of Yangquan Coal Industry Group was mechanical extraction type,which adopts central parallel ventilation,and the return air shaft was return air inclined shaft,jointly responsible for the ventilation task.Empirical calculation shows that the ventilation system can not meet the ventilation requirements after the integration of the mine.It is necessary to upgrade the main ventilation equipment of the mine and optimize the ventilation system of each mining area.
