煤矿冲击地压灾害的预防与治理

Prevention and Management of Bump Hazard in Coal Mines

摘要:

本文在分析华丰矿区地质开采环境特征的基础上,探讨了冲击地压形成的内外因和内在斑裂产生的机理。建立健全了灾害预测防治体系,提出了开采解放层、煤层注水、爆破卸压等治理防护措施。

Abstract:

On the basis of analysing geological mining environment of Huangfeng coal area,internal origin,external origin which caused bump and mechanism of forming internal phyric cracks are studied in this paper.hazard predication and prevention system are established,and countermeasures,such as mining strat,waterflood and realising pressure by explosion are put forward as well.
