Abstract
Large-scale separation terrane in bending strip upside cranny strip is brought by un-consistency of overlying strata subsidence movement due to underground mining. Different characters of movement and deformation of overlying strata and ground include periodic caving of separation terrane interspace along with work face mining. Conglomerate rock layer movement is the main power fountain of rock burst on the basis of locale observation. And rock burst moves periodically adapt to movement of deep conglomerate rock layer which had similar characters with main roof. Practice indicates this method that forecasting and prediction using correlation information of movement of strata and ground is feasible and has reference meaning for similar stope.
