西铭煤矿48502A掘进工作面通风计算及通风路径设计

Ventilation calculation and ventilation path design for 48502A heading face in Ximing coal mine

以西铭煤矿48502A掘进工作面为研究对象,分别以瓦斯涌出量、二氧化碳涌出量、工作面爆破最大炸药量和同时作业人数为变量确定了工作面所需风量,利用最小、最大风速进行风量验算,确定了掘进工作面需风量为404m^3/min。设计两条通风路线和一条回风路线,保证掘进工作面的通风量,确保掘进工作面安全运行。

Taking 48502A heading face of Ximing coal mine as research object,the required air volume of the working face is determined by gas emission,carbon dioxide emission,working face blasting maximum explosive quantity,and number of operators at the same time,Airflow calculation using minimum wind speed and maximum wind speed,It is determined that the required air volume of the heading face is 404m^3/min.Design two air supply routes and one return air route,ensure the ventilation of the heading face,ensure safe operation of the heading face.
