摘　　要：以金佳煤矿金一采区煤层群下保护层开采为对象,通过相似模拟试验裂隙发育的变化情况来研究下保护层开采卸压瓦斯运移通道及富集区,得出了瓦斯运移和赋存随下保护层工作面推进的变化规律,用以指导煤层群开采时的瓦斯治理工作。The paper is based on gold -one mining area of under- protective layer mining in Jinjia mine, through similar simulation test of fissure development changes to study protective layer mining pressure relief channel of gas migration and accumulationarea. The change rules is concluded that the change law of gas migration and accumulation with the lower protective seam advancing, it can guide for coal mining gas control work.
