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.

The parameters in the DPC model were calibrated based on experimental compaction tests using an Instron 5566 test machine, including single punch die compaction, unconfined axial compression and diametrical compression. In the experiments, iron ore powders with the size 25–75 μm were dried in an oven for 12 h, then were mixed with 5% water.
