摘　　要：下向分层进路式尾砂胶结充填采矿法顶板为胶结充填体,深部回采,顶板的稳定性直接关系到整个回采过程的安全.在充填体中布置钢筋可提高顶板自身的稳定性.通过对充填体中横向布筋与纵向布筋分别建立模型进行相似模拟试验,通过试验结果及试验过程监测数据分析,判别了顶板充填体的破坏机理,提出了充填体中布筋的合理方式,提高了顶板的稳定性,确保了回采过程的安全.The roof is cemented filling body in underhand drift cut-and-filling stopping,and its stability is the key to safety mining of deep zone.Roof stability can be improved by distributing reinforcement in the filling body.Failure mechanism of the roof filling body was revealed through the result and the analysis of the monitoring data from the similarity simulation model test of lateral and longitudinal reinforcing pattern of the filling body.The reasonable reinforcing pattern was put forward to improve the stability of the roof and to ensure the safety mining.
