摘　　要：针对综放采场开采过程中瓦斯频繁超限现象,对综放采场矿压与卸压瓦斯运移关系进行了分析研究,通过理论分析、现场实测和数值模拟相结合的方法得出综放采场矿压与卸压瓦斯运移关系。Aimed at the phenomenon of gas transfinite frequently in fully-mechanized top coal caving,the relation between strata behaviors and relieved gas delivery for fully-mechanized top coal caving is studied, used the combined method which include theoretical analysis, field measurement and numerical simulation show that relation between strata behaviors and relieved gas delivery for fully-mechanized top coal caving.
