摘　　要：基于注浆减沉的理论与实践 ,本文提出了井下开采控制与覆岩注浆相结合的沉陷控制方案 ,即跳采与注浆相结合和条采与注浆相结合的综合方案 ,分析了各方案的覆岩移动变形规律和存在的相关问题 。On the basis of theory and practice of reducing subsidence by grouting, the authors proposed two subsidence control methods by combination of mining control and grouting, internal mining grouting and strip extraction grouting. Overburden deformation laws and related problem are analyzed. The study has important meaning in improving reclamation ratio of coal resource and subsidence control.
