It may fail catastrophically if the load frame is “soft”. Example below is for a “stiff” frame. • The compressive strength of rock is a function of the confining pressure. • As the confining pressure increases so does the strength. Goodman, Intro to Rock

Compressive Strength of rock: The RMR value depends up on the unconfined compressive strength (q u ) of the rock and it can be determined from laboratory compression test on a prepared rock specimen. Or otherwise find out the approximate value of compression strength from point load test on intact pieces of drill core.Performance analysis of drilling machines using rock,coefficient of rock strength (CRS) and percentage of quartz, and established linear predictive equations. They stated that the established equations can be used for the prediction of the performance data of percussive drills.

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.

Knowing the rock type and rock material hardness, it is possible for the experienced engineer or engineering geologist to make fairly accurate estimates on rock material strength. These can be readily verified by uniaxial compressive strength or point load tests. A simple estimate can be made from the field test in Table 5.Rock properties OoCities,a) Rock Hardness. Rock hardness is a term used in geology to denote the cohesiveness of a rock and is usually expressed as its compressive fracture strength. Terms such as hardrock and softrock are used by geologists to distinguishing between igneous/metamorphic and sedimentary rocks, respectively.
