多级柔性防冲密闭技术研究

Research on Multi-stage Flexible Anti-scour Sealing Technology

针对传统密闭方式不能满足矿井冲击地压和防灭火安全的缺点,通过双墙夹墙密闭施工技术、采空区空巷充填技术、密闭外加设钢丝绳悬挂全断面金属网技术形成多级柔性防冲密闭技术,能够最大程度地减少密闭区内自然发火与冲击地压风险,提高矿井密闭治理水平,提升矿井安全生产保障能力。

In view of the shortcomings that the traditional sealing method can not meet the mine rock burst and fire prevention safety,through the double-wall clamping wall sealing construction technology,goaf roadway filling technology,sealing plus wire rope hanging full-section metal mesh technology to form multi-stage flexible anti-impact sealing technology,it can reduce the risk of spontaneous combustion and rock burst in the closed area to the greatest extent,improve the mine sealing management level,and enhance the mine safety production guarantee ability.
