通风系统作为矿山生产中的重要组成部分，直接关系工人的工作环境和矿山的安全生产。针对龙头山金矿矿体赋存条件和开采现状，提出了通风系统优化改造方案，采用抽出式通风，通过砌筑风墙，增加风门、调节风窗，增加风流路径，优化通风网络布局，增加通风构筑物，减少风流阻力，提高通风效率。新的通风系统不仅提高了通风效率，改善了工作环境，还提升了生产效率和安全生产水平，实现了经济效益的显著提升。详细阐述了优化改造的具体内容、实施步骤及取得的效果，旨在为类似矿山的通风系统改进提供借鉴和参考。  

Asa vital componentofmine production, the ventilationsystemdirectly affects workers' workingenvironment and the safety of mining operations. In view of the orebody occurrence conditions and current mining status at the Long-toushan Gold Mine, a ventilation system optimization and renovation scheme was proposed. The system adopts an exhaust ventilation mode, incorporating construction of air walls, addition of air doors and adjustable air windows, expansion of airflow paths, optimization of the ventilation network layout, and installation of additional ventilation structure, to reduce airflow resistance and improve ventilation efficiency. The new ventilation system not only enhanced ventilation efficiency and working conditions, but also significantly boosted production efficiency and safety, leading to notable economic benefits. This paper presents the specific content of optimization and renovation, implementation steps, and resulting effects in detail, aiming to provide references and guidance for ventilation system improvements at similar mines.
