综合运用井下密闭技术 确保矿井安全

Comprehensively Using Underground Fire Sealing Technique to Guarantee Mine Safety

通过理论分析对比和现场考察,阐述了淮北桃园煤矿运用井下密闭技术防灭火、在便于排放水的同时确保通风系统稳定、密闭抽排瓦斯、消除采煤工作面瓦斯积聚的基本方法,研究了密闭技术的现场使用条件及技术参数,提出了矿区密闭技术综合运用的新思路。

Based on the theoretical analysis and comparison and on-the-spot investigation, the basic method of using underground sealing techniques to control mine fire, guarantee stability of ventilation system and gas drainage and eliminate gas accumulation in coal face are described, research on the site application conditions and technical parameters of the sealing techniques is conducted, and a new thinking of the complex application of mine sealing techniques is put forward.
