ABSTRACT
Understanding the mechanical behavior of salt related to roof stability of drifts is of crucial importance for the safety of workers and installations in mines. In its potash and rock salt mines K+S uses different measures and instruments to collect geomechanical data and to monitor roof stability. Examples of the various methods to monitor the roof behavior are discussed for the potash mine Werra and the rock salt mine Borth. This monitoring supplies quantitative data for further geomechanical interpretation and is the base for a prognosis of the development of roof stability.
