摘要
在分析沿空留巷顶板破断垮落特征的基础上，论述了沿空留巷护巷带参数的设计思想和设计方法，结合高水速凝材料巷旁充填沿空留巷技术的实例，阐述了这种设计方法在沿空留巷技术中的实际应用情况．实例证明，用这种方法设计沿空留巷护巷带参数所获得的技术效果和经济效益显著。
Based on analysis of roof collapsing characteristics in gateways maintained along the goaf,the design concept and method for designing gateway side packing parameters is described.Examples of maintaining along the goaf a gateway by packing with quick setting materials with high water content are given.It is proved that the technical and economic benefits of this method are remarkable.The method is of important significance to the practice.
