HIGH-PRESSURE FILLING AND GROUTING TECHNIQUE FOR CONTROLLING STRATA MOVEMENT

Abstract

Abstract

The large cracks are inevitable outcome of the strata movement. The surface subsidence wasgreatly retarded by filling consolidation grouting material into the cracks. In this paper the authors discuss highpressure grouting equipment and its technological process, selection of grouting material and determination ofgrouting parameters.
