工作面局部通风技术的优化及效果分析

Optimization and Effect Analysis of Local Ventilation Technology in Working Faces

为解决随着工作面断面面积增大、巷道延长所导致的工作面通风能力无法满足实际需风量的问题,在对某煤矿通风现状进行分析的基础上,结合其现场情况拟提出两种优化方案并对方案进行对比得出最佳方案完成了通风机和井筒的重新选型;最后,通过现场测定对通风技术的优化效果进行评估,并取得理想结果。

In order to solve the problem that the ventilation capacity of the working face cannot meet the actual air demand due to the increase of the cross-sectional area of the working face and the extension of the roadway,based on the analysis of the ventilation status of a certain coal mine,two optimization plans are proposed and compared with the other plan to determine the best plan.The re selection of the ventilation fan and shaft is completed.Finally,the optimization effect of ventilation technology was evaluated through on-site measurement and ideal results were achieved.
