Blasthole Cone Sampling Experiments for Iron Ore

Blasthole cone samples are used for grade control in most of the iron ore mines of the Pilbara of Western Australia. This method of sampling is straightforward when the target sampling interval matches the mining bench height but is problematic when the blasted bench is ‘flitch’ mined in two or more passes. Crucially, the sampler needs to decide which part of the blast cone represents the
