    • Abstract
  • Based  on  the  results  of  field  observation,  simulation  model  experiment  and  numerical  analysis  ,  the  seam  conditions  that  affect  the  top  coal  caving  and  drawing  characteristics  in  the  sub-level  caving  mining  are  analysed.    The  critical  values,the regularity and  sequence of influence   of  several  conditions  are  put  forward.    The  forecasting  formula  and the classification   for  the  top  coal  caving  and  drawing  characteristics  of  different  seams    are  obtained.
