摘　　要：基于综放沿空留巷围岩变形规律,建立了合理的物理力学模型来计算出巷旁充填体稳定所需要的整体支护强度与可变形能力,并结合现场地质条件与高水材料的特性,最终确定了沿空留巷的合理设计方案,工程实践也获得了成功,最终变"双U"型通风为"Y"型通风方式,基本解决了上隅角瓦斯超限问题,为今后综放沿空留巷提供了一定的实践经验。Based on the deformation law of surrounding rock of the gob-side entry retaining in fully-mechanized coal faces with top-coal caving. The reasonable physical mechanics model is built to calculate the basic support strength and deformation capacity of the filling body beside the roadway, combined with the site geological conditions and the characteristics of the high-water material, the reasonable design scheme of the gob-side entry retaining was determined ultimately. The engineering practice had already achieved succeeded, eventually double ＂U＂ type ventilation way was changed into ＂Y＂ type ventilation one and the problem of gas overrun in upper comer was settled basically. Those could have certain guidance to the practice experience of the gateway retained along goaf in the future
