The uniaxial compressive strength of a rock under static loading often decreases with an increasing temperature at which the rock has been heat-treated before strength testing. This conclusion is drawn from a great number of experiments [1,2,4,8,9,11,17–19].The higher the temperature is, the lower the strength. Some results for uniaxial …

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. C 0 …

The equation for Rittinger's Law can be written as: E = K R f c (1/L 2 – 1/L 1) Where: E=Energy, K R =Rittinger's Constant, f c =crushing strength of the material, L 1 =initial length, and L 2 =reduced length. Kick's Law states that the energy is proportional to the size reduction ratio. The equation for Kick's Law can be written as:
