摘　　要：通过对采煤工作面回风巷上穿层钻孔抽采被保护层卸压瓦斯试验,探讨了采煤工作面回风巷上穿层钻孔布置原则,分析了影响回风巷穿层钻孔抽放被保护层卸压瓦斯效果的原因。This paper introduces the drain - gas experiment from protected coal bed using upper penetrating coal beds holes from return airway in mining working place, and arrangement rules of upper penetrating coal beds holes from return airway are discussed, and the reason that effects on drain gas using upper penetrating coal beds holes from return airway in mining working place is analyzed.

关 键 词：采煤工作面 穿层钻孔 被保护层 抽放瓦斯
