    2015-3-27  Failure of the shaft lining: The most frequent failures of the shaft lining result from a decrease of its strength or from an increase of the pressure of surrounding rock. When the strength of the lining is exceeded, the lining (bricks, stone blocks, concrete, cast iron and steel) deforms and eventually breaks.
