华阳二矿通风系统的改造及通风机的选型

Transformation of ventilation system and selection of fan in Huayang No. 2 Coal Mine

矿井通风系统是保障煤炭安全生产的首要条件,其性能与煤矿工作面的安全性、高效性呈正比关系。为提高华阳二矿71509工作面通风系统的可靠性,针对该工作面通风存在问题和实际状况,决定对通风系统进行改造,措施为增设回风井、辅助回风井和回风斜井,并结合工作面的工况,最终决定通风系统配备FBCDZ-8-No30C-2×630型通风机。实践表明,改造后完全满足生产需求。

Mine ventilation system is the primary condition to ensure the safety of coal production,and its performance is proportional to the safety and efficiency of coal mining face.In order to improve the reliability of the ventilation system in 71509 working face of Huayang No.2 Coal Mine,in view of the existing problems and actual conditions of the ventilation system in the working face,it was decided to transform the ventilation system.The measures were to add return air shaft,auxiliary return air shaft and return air inclined shaft.Combined with the working conditions of the working face,the ventilation system was finally determined to be equipped with FBCDZ-8-No30C-2×630 ventilator.Practice shows that the production needs are fully met after the transformation.
