Description	The pressure resulting from the interaction of the shaft lining and the rock mass, produces shaft lining resistance. The paper gives a graphic presentation of the effects of shaft lining resistance on the size of the plastic zone around the shaft, based on the stress calculation accomplishment by an MCAD programming package. This chapter provides a graphic presentation of the effects of shaft lining resistance on the size of the plastic zone around the shaft, based on the stress calculation accomplishment by an MCAD programming package. The calculations carried out by the MCAD programme pack resulted in values for the boundaries of the plastic zones and stresses within plastic and elastic areas for the certain values of shaft lining resistance. For thus obtained values a graphic presentation is given illustrating the influence of shaft lining resistance on the size of the plastic zone around the shaft. The value of the required shaft lining resistance may be obtained from the characteristic rock mass lines and a selected lining. In case when after excavation the lining is set in the shaft, the components of normal stress along the shaft contour will decrease to null, and the components of normal stresss will have maximum value.
