ROCK MECHANICS IN THE 1990S

Following specific test procedures, the new penetrometer method was determined to produce reproducible results for estimating shale compressive strength. It can be inferred from the results that the penetrometer test was not as useful in the tests reported in this paper for hard shales in that a high degree of scatter was observed for the hard Mancos shale. The scatter can be attributed to the extreme hardness of Mancos shale which pushed the equipment to its limits. A relatively low scatter can be observed for the soft Wellington shale. The main conclusions which can be drawn from this paper are as follows: (1) A good correlation exists between the penetrometer test results and the uniaxial compressive strength results for the shales tested. This provides an easy method for determining relative compressive strengths of shales; (2) A penetrometer test has been modified and adapted to determine the penetrometer hardness of shales; (3) Penetrometer tests can be performed on relatively small samples, under atmospheric conditions, which makes it adaptable for field testing; and (4) Many tests can be carried out in a short time and the penetrometer equipment required for testing is easy to assemble. This paper was presented at the 34th U.S. Symposium on rock mechanics, 27-30 June 1993, University of Wisconsin-Madison. For the covering abstract see IRRD 863389.
