Methodology for cleat angle characterisation from drilling cuttings using quantitative image analysis

This methodology characterises the preferable cleat angles and cleat spacing form frilling cuttings of coal seams. This angle distribution is of use for modelling sub-surface cleat orientations. The measurements are performed using the Image analysis program Qwin form Leica Microsystem. Microsoft Excel is used for the processing of the measured data.

The procedure involves:
- Preparation of the sample: Crushing and sieving.
- Scanning and acquiring multigrain images.
- Separation of multi grain images into single particle images.
- Gathering shape information using the rotation program.
- Processing image analysis results.
