1、 1 石门揭煤设计石门揭煤设计 摘摘 要要：在煤与瓦斯突出矿井中，石门揭突出煤层危险性大，时间特别长，是矿 井安全技术的重点和采掘部署的瓶颈工程。本文阐述了国内外关于煤与瓦斯突 出机理的综合学说，详细分析了石门揭煤突出的原理，包括其突出影响因素、 发生条件、突出煤体的力学特性与瓦斯流动规律，之后对通过对平行布孔抽放 瓦斯、扇形布孔抽放瓦斯、交叉布孔抽放瓦斯比较，提出平煤八矿戊9-10煤层 的揭煤方案石门短导硐、 交叉布孔抽放瓦斯和震动放炮相结合的揭煤措施。 并按防治煤与瓦斯突出细则制定了“四位一体”防突措施及相关安全防护 及防突措施。 关键词关键词：煤与瓦斯突出，石门揭煤，突出机理，短导硐揭煤
