was conducted within a variety of material packings (as shown in Table 1 and Figure 1) including saturated clay, saturated coal, mine water and grout/cement. Rock bolts and cable bolts used in these experiments were the same types utilized at a longwall underground coal mine in the Sydney Basin, Australia. The mill scale layer from every bolt was removed prior to the experiments. This mill scale, which......
