摘要
矿井原有通风系统受采动影响,巷道损坏严重,且存在回风路线长、通风阻力大、系统复杂、安全可靠性低等不足。通过对矿井Ⅱ7采区西翼通风系统分析,选择优化改造方案,并对方案的技术可行性、经济合理性、安全可靠性进行比较分析。
Due to vibration caused by mining activities, the tunnels are seriously damaged. Besides, the original underground ventilation system has the disadvantages such as long air return way, great ventilation resistance, complicated structure of system, low degree of safety ＆ reliability. The ventilation system of No. 7 stope of mine II is analyzed. On the basis of analysis, an optimization ＆ improvement scheme is established; and its practicability, techno- economic reasonableness and safety ＆ reliability are discussed.
