A FRACTURE-DAMAGE MODEL OFTHE DAMAGING PROCESS OF SURROUNDING ROCKMASS/COALAROUND STOPE

  • The constitutive relations undercompressionshearing and tension-shearing stressstates are derived regarding discontinous jointedrockmass and coal as damaged inedium and con-sidering different stress states.These relations areapplied to analyse rock movement and damage frac-ture.The caculated result agrees well with themeasured data and can be used to estimate rockmovement and stress.
