THE STUDY OF STRUCTURALPLANE BASED ON APPEARANCE AND BACKFILLING STATE

Discontinuity of structuralplanes appearance is a complex research object; however,it has important an influence to the mechanical properties. At the present time,the study of incompletely backfilling of structuralplane is very poor. The adhesive friction theory is applied to research the changing course of structural plane,which is based on the analysis of incompletely backfilling．
