A CONDITIONING METHOD FOR ARGILLACEOUS ROCK CORES HAVING DISKING PROPENSITY WITH THE INFLUENCE OF WATER
Abstract
In Turkey in the Tuncbilek coal basin, the subject area of this study, there are gray and brown colored marl formations. As known, the test specimens shall be conditioned in such a way as to be reached to the natural water content before the strength tests, and it is preferred to use the saturated specimen in order to be representative for levels below the groundwater. It is noticed that the gray marl core samples taken from Tuncbilek were broken into parallel slices by the influence of water in less than half an hour. In this study, instead of directly treatment with water, the conditioning studies on the Tuncbilek marl samples were carried out in a climate cabin and, it was determined that the marl moisture holding capacity increased when the environment humidity increased and/or temperature decreased. As a result of these conditioning studies, the optimum conditioning for the marl of this region was found to be 17.6 oC temperature and 90 \% Relative Humidity (RH) by taking working efficiency of the climate cabin and underground mine climate into consideration. Besides, the triaxial compression strength tests were carried out on the dried samples and on the samples which were subjected to conditioning. According to the test results, geomechanical material properties were determined in order to be used for future studies that will be conducted at this region.
