摘要
针对某煤业采用中央分列式机械抽出式通风工艺,利用矿区主、副平硐作为进风井,并设置回风斜井,以及存在的总供风量不足、进风风阻大且通风网络复杂等问题进行通风系统优化研究,探究供风量不足、风流串联以及风阻分布失衡要素,设计增设了二盘区进风斜井和二盘区回风斜井,使 4-2 煤—5-2 煤与 2-2 煤—3-1 煤的通风路线相互独立,依靠自然分风进行通风系统的优化.经过对风量分配、等积孔、风阻分布以及通风网络的计算分析可知,优化后的通风系统有效解决了原系统存在的问题,优化效果明显.
Abstract
In response to the adoption of a central split mechanical extraction ventilation process in a certain coal industry,using the main and auxiliary adits of the mining area as intake shafts,and setting up return air inclined shafts,this study aims to optimize the ventilation system by addressing issues such as insufficient total air supply,high intake air resistance,and complex ventilation network.The study explores factors such as insufficient air supply,air flow series connection,and imbalanced distribution of air resistance.A two panel intake inclined shaft and a two panel return air inclined shaft are designed and added,making the ventilation routes of 4-2-5-2 coal and 2-2-3-1 coal independent of each other.The optimization of the ventilation system relies on natural air distribution.After calculation and analysis of air volume distribution,equal volume holes,wind resistance distribution,and ventilation network,it can be concluded that the optimized ventilation system effectively solves the problems existing in the original system,and the optimization effect is significant.
