Estimating compressive strength. General rock failure criterion can be reduced to a few parameters dependent on lithology (m) and the uniaxial compressive strength (C 0). Lithology is commonly derived during log analysis so m may be estimated (Table 1). What is needed still is an initial measure of rock strength provided by C 0.

Rocks are rated on the on the Moh s Hardness Scale which rates the rocks on the scale from 1 to 10. Rocks with hardness 1-3 are soft rocks from 3-6 are medium hardness rocks and 6-10 are hard rocks. The hardness of Basalt is 6 whereas its compressive strength is 37.40 N/mm 2. Streak is the color of rock when it is crushed or powdered. The
