摘　　要：针对资源整合矿井公共风路稳定性差的问题,提出了"整合自然风压"的概念;通过分析"整合自然风压"产生原因及条件,绘制出"整合自然风压"特性曲线图;进一步分析"整合自然风压"与风机风压的大小和方向变化时公共风路风流稳定性的变化,得出影响公共风路稳定性的8种致因模型。结合金阳、南宁两矿资源整合实例,在两矿风机风压不变的情况下,公共风路在春、夏、秋三季的风流方向与冬季的风流方向相反。应用结果表明,"整合自然风压"对公共风路风流方向有决定性影响。To improve poor stability of public wind road in resource integrated mine,the concept of integrated natural wind pressure was proposed.By analyzing the causes and conditions,the characteristic curve of the integrated natural wind pressure was drawn.Moreover,the stability variation of public wind was analyzed when the quantity and direction of the integrated natural wind pressure and the fan pressure were changed.Accordingly,eight causation models influencing on public road stability were established.Combined with two mine resource-integrated examples in Jinyang and Nanning,it was found that the airflow direction of public wind in spring,summer and autumn was contrary to that in winter.Application results showed that the integrated natural wind pressure had dominated impact on the airflow direction of public wind.
