A study on the Correlation Between Orientation of Joint Sets and Location of Subsidence Zone in Subsidence Area

Abstract

Joint sets should be considered as an influence factor, when location of subsidence zone by stopes is predicted. And the mechanical properties and distribution patterns of joint set above stopes may be affecting subsidence occurrence. In this study, therefore, the orientation of joint sets is reanalyzed with the data from the previous research on prediction of defining the subsidence zone. From a correlated analysis, the influence of major joint set(  ) on subsidence location was analyzed by comparing the angle of assumption with the angle of major joint set(  ).
