Abstract
In the framework of the CEC Programme on Radioactive Waste Disposal (1985-1990), in situ experiments in the Asse II salt mine in Germany are conducted. This report describes the work of the 600 m borehole project performed during the contracting period August 1986 - December 1990. During this period measurement devices for measurement of rock mechanical parameters have been developed and were made operational. For the drilling of the boreholes a new technique has been developed. One main subject of investigation was to develop an on-line method to determine the gas content in the flushing air during drilling operation. The method used worked satisfactorily and the test showed that this surveillance method could be used during dry-drilling of deep emplacement boreholes in a future repository. For the second experiment the Variable Pressure Device (VPD) has been constructed to measure the elastic and time-dependent response of the salt on pressure changes. 37 refs., 49 figs., 5 tabs.
