摘　　要：为了分析杨柳煤业10416工作面通风系统调整以后,风量增大而工作面回风巷瓦斯浓度下降不大、风排瓦斯量增大的原因,分析了通风系统调整以来通风设施及采掘的变化情况及其对工作面风排瓦斯量及10414工作面采空区漏风的影响。通过分析认为影响因素有:通风系统调整引起风量和风阻的变化;临时通风设施的影响;邻近的10412工作面回风巷局部通风机的影响;采掘条件变化的影响等,其中通风系统调整及10412工作面回风巷局部通风机是主要原因。In order to find the reason for gas concentration decreasing little and the amount of gas through ventilation increased in the working face of return airflow roadway after ventilation system adjustment in NO. 10416 working face of Yangliu Coal Industry Company, it analyzed the changes of ventilation facilities and mining situation, and their effects on the amount of gas by ventilation and goal leak- age of NO. 10414 working face since the ventilation system adjustment. Through the analysis, it obtained the influence factors, which included the variation of air - volume and ventilation resistance caused by ventilation system adjustment, the influence of temporary ventilation installation, the effect of neighbor local fan in the return airflow roadway of NO. 10414 working face, the changes of mining condition and so on. The main reasons were the ventilation system adjustment and local fan in the return airflow roadway of NO. 10414 working face.
