陕西彬长大佛寺煤矿矿井通风系数考察研究

Investigation and Research on Coal Mine Ventilation Coefficient for Dafosi Mine in Bingchang Mine Area in Shaanxi Province

对彬长矿区大佛寺矿井主要进回风井,采掘面等地点风量以及一个综采工作面,两个综掘工作面瓦斯涌出量半年的实测统计、考察研究,得出了适合本矿井的通风系数、采掘工作面瓦斯涌出不均衡系数,对加强矿井通风管理,合理分配风量,提高有效风量率具有重要意义,对矿区后续开发的矿井和条件相类似的煤炭企业通风管理具有借鉴意义。

Based on the measured statistic figures of air quantities in main downcast and upcast air shafts, in coal work face and heading faces and the gas outflow from one fully mechanized coal face and two fully mechanized heading faces in Dafosi Mine in Bingchang mine area for half year and based on the research work, the authors have obtained a ventilation coefficient suitable for this mine, and the irregular factor of gas emission from the coal mining and heading faces. This is of great importance to the strengthening of coal mine ventilation management, rational distribution of air quantity and improvement of effective air quantity rate in this mine. It is also can be used for reference in ventilation management in mines to be developed within this mine area and in coal enterprises with similar conditions.
