This paper discusses the various types of en echelon ore veins and points out their characters and regularity. And, in connection with model experiments the mechanism of formation of en echelon ore veins is analyzed. It is suggested that the generation and development of the ore veins under study could be attributed to shear strain followed by tension strain. Finally, from theoretical and practical viewpoint the author illustrated the regularity of en echelon ore veins.
