The paper performs the standards of shaft lining inspections used in Poland. They comprised four criterions: lining homogeneity, level of its corrosion, watertightness and load bearing capacity of the lining and the limit values for every criterion were worked out. If even one of above criterion is not met the repair works have to be taken. The example of shaft investigation and technical recommendations for the lining repair is shown as well. It is proved that only a comprehensive approach to the condition of the shaft lining can allow proper assessment of its performance for the next years.
