Abstract: Based on ores movement regularity and characteristics of the mine shafts from the previous，through the observation of deep shafts in Heigou mine where wellbore plugging accident often occur，the deep shafts existence characteristics of vertical full section phase ores moving is found on top of the vertical full section continuous ore moving zone.This feature is generated by the arches effect of the ores flow in the shaft，and the formation and destruction of the arches in the wellbore are carried out alternately，so that the ores discharge shows like the pulse; It is concluded that the deep shafts ores movement rules include the phase movement of the vertical full section，the continuous movement of the vertical full section，the variable speed and direction movement of the vertical full section and the variable speed and direction movement of the vertical part section；The characteristics of phase and vertical full section ores movement is the important reason for wellbore plug，wall caving，wear and ore mixing and grading by analysis.At the same time，the processing technology of the plugging wellbore is put forward for the present deep shafts，For the design and construction of the new shafts，the design form of wellbore structure to prevent blockage is put forward；It opens up the new idea for trouble clearing appearing in deep shaft，and this idea is an important guiding significance on the design and practice of production of the same type of deep shafts.

Key words: Deep shaft, Wellbore plugging, Granular material, Movement regularity
