  • Patent number: 9689258
    Abstract: A water-preserved-mining roof-contacted filling method for controlling fissure of overlying strata and surface subsidence. The method is suitable for controlling fissure of overlying strata and surface subsidence in water-preserved-mining of a mine. A sensor is mounted at the top of a goaf of a filling working face where water-preserved-mining is carried out, and a filling body that is filled is monitored through a stress display device so as to determine whether the goaf is roof-contacted or separated. When the filling body is separated after roof-contacted, the goaf is filled for the second time so as to be roof-contacted fully, so that the purpose of controlling fissure of overlying strata and surface subsidence can be achieved, and protective mining of water resources of the mine can be realized at last. The method is simple and targeted, and has strong operability and high efficiency.
