摘　　要：针对余吾煤业有限公司瓦斯高,煤层厚度大,综采放顶煤等特点,为解决工作面上隅角瓦斯超限的问题,在N1102工作面回风尾巷采用高水速凝材料巷旁充填沿空留巷技术。通过建立力学模型求解巷旁充填体所需强度,确定合理的沿空留巷设计方案,现场应用获得了良好效果。For the features of high gas, large thickness of coal seam, fully mechanized top coal caving in Yuwu Mining Company, to solve the problem of gas overrun in upper comer, we apply gob -side entry retaining technology at N1102 working face of tail ventila- tion roadway with high - water rapid hardening material roadside filling body. We calculate the required strength of filling body through the mechanics model, and determine the reasonable design scheme for gob - side entry retaining. Field application achieved good effect.
