摘要
针对义城煤矿过空巷矿井通风系统出现风流短路等问题,提出减少无效风量的方法,并施以具体的研究方案:缩短通风距离、封闭采后区域和无效巷道等。工程结果表明:该方案减少了矿井无效风量,解决了原通风系统存在的问题,优化了义城煤矿过空巷矿井通风系统,为其他类似矿井提供可参考的合理方案。
In view of the short circuit of ventilation system in the mine ventilation system of Yicheng Mine,a method to reduce the invalid air volume was put forward,shortening the ventilation distance,the closed post mining area and the invalid roadway.The results of the project showed that after the optimization of the ventilation system,the invalid air volume was reduced,the existing problems of the original ventilation system were solved obviously,and the ventilation system of the Yicheng Mine was optimized,which provided a reasonable scheme for other similar mines.
