Mar 01, 2003 The general characteristic of all these methods is the need for either a Bond mill or a standard laboratory mill. A different, non-standard method for determining the Bond work index was presented using an experimental relationship between the Bond work index and the mechanical and elastic properties of the material (Yap et al., 1982).

Broch and Franklin (1972) proposed a testing method called the Point Load Test. The test consists of squeezing pieces of rock diametrically between two hardened steel cones. The test set-up is shown in Figure 1. For these tests, rock pieces must have a length at least 1.4 times their diameter (Figure 2a). The point load index, Id, is equal to
