摘　　要：地表沉陷控制的关键是治理覆岩破坏。控制覆岩破坏的途径有多种,覆岩离层注浆减沉技术是一种控制覆岩破坏的新方法。本文介绍了该技术在国内外的应用情况,论述了注浆减沉的理论基础和减沉机理,并提出了下一步要解决的问题,为提高减沉率和推广该技术奠定了基础。It is a base for controlling surface subsidence to decrease the broken of cover stratus and there are many ways to do it. The technology of injecting grouts in separated layers to decrease subsidence is a new method. The application of grouting surface subsidence control technology with grouting to separated layers in rock overburden is presented at home and abroad, and the theory basic and principle of grouting to decrease surface subsidence are introduced. Some problems are presented to establish the base for increasing ratio of decreasing surface subsidence and spreading it.
