ANALYZING ON GEOLOGICAL CONDITIONS AFFECTING EFFECTIVENESS OF REDUCING SUBSIDENCE WITH GROUTING INTO SEPARATING ZONE

    摘要
  • 摘要: 煤层开采后,采空区上覆岩层内产生离层现象,注浆充填离层可以减小地面沉陷。覆岩离层注浆减沉效果受离层带地层条件、离层围岩透水性和工程地质特性的影响,表现为离层的形成、宜于注浆的离层带的位置、注浆液的保存与支承力的维持。

     

    Abstract: The separating zone in the overlying strata is formed after mining.The technology of separating zone injection can be used to prevent the mining subsidence.The effectiveness of reducing subsidence by injection is affected by overlying strata geologic conditions,such as lithologic factor,seepage,and engineering geological characteristics.
