煤矿局部通风技术的优化与效果比较

Optimization and Effect Comparison of Local Ventilation Technology in Coal Mines

为进一步提升煤矿工作面的通风效率,通风机的运行效率等,为保障工作面安全生产奠定扎实基础,在对矿井基本情况包括有煤尘、瓦斯涌出量、二氧化碳涌出量等分析的基础上;根据局部通风技术优化原则和依据优选通风方案,并完成局部通风机的选型和配套风筒的选型;最后,对局部通风技术的优化效果进行比对。

In order to further improve the ventilation efficiency of coal mine working faces and the operational efficiency of ventilation fans,and to lay a solid foundation for ensuring safe production of working faces,based on the analysis of the basic situation of the mine,including coal dust,gas emission,carbon dioxide emission,etc.Based on the optimization principles of local ventilation technology and the optimization of ventilation schemes,complete the selection of local ventilation fans and matching air ducts.Finally,compare the optimization effects of local ventilation technology.
