摘　　要：为解决矿井采空区和巷道瓦斯超限的问题,文章通过建立瓦斯运移模型对采空区瓦斯运移规律展开分析,发现采空区沿空留巷侧中部位置更易聚集漏风流,从而导致该区域瓦斯浓度显著升高。通过调整配风比和抽采流量,文章采取了优化措施,有效降低了巷道及采空区的瓦斯浓度,降低了巷道风压,从而为提升矿井的安全生产水平提供了技术支持。In order to solve the problem of gas overrun in mine goaf and roadway,this paper analyzes the gas migration law in goaf by building a gas migration model,and it is found that the middle position on the side of gobside entry retaining in goaf is more likely to accumulate air leakage flow,which leads to a significant increase in gas concentration in this area.By adjusting the air distribution ratio and extraction flow rate,optimization measures have been taken to effectively reduce the gas concentration in the roadway and goaf and reduce the wind pressure in the roadway,thus providing technical support for improving the safe production level of the mine.
