WebMay 4, 2012 · The Drilling Rate Index (DRI) is assessed on the basis of two laboratory-tested parameters: the Brittleness Value S 20 and the Sievers’ J-value (SJ). The brittleness test gives a measure of the mechanical properties of a rock sample. The test consists of two parts (Dahl 2003 ): WebBrittleness is an important parameter controlling the mechanical behavior and failure characteristics of rock under loading and unloading, such as the fracability, cutability, drillability and rockburst proneness. As such, it is of high practical value to correctly evaluate the rock brittleness.
