Geomechanical problems on using former potash mines as high pressure storage for gas. (In German). W. Minkley and W. Menzel. Erdol Erdgas Kohle, June 1995, 111(6), 260--265.
The need is stressed for the stability and impermeability of the underground workings over a period of decades to be proven prior to their use as storage for natural gas. Details are given of how calculations of the time-dependent system behaviour under the altered cyclic stress conditions and of the dynamic system stability show the stability of the mining site can be proved and the observation requirements when dimensioning the sealing structure. Experimental research results are presented of the permeability of salt rocks and the stress relief of the obturating salt rock layers in the centre subsidence area of the mines. A method of determining maximum permissible storage pressure is reported. 7 refs.
