【 摘 要 】

This third quarterly technical report discusses the progress made on a machine vision technique for determining coal content and ore grades. The work done this quarter has utilized a miniature imaging spectrometer. Procedures to collect and process the spectral and spatial data from the imaging spectrometer have been established, and software routines have been employed to use this data to differentiate sulfides from background rock in platinum/palladium core samples. These sulfides are indicator minerals for high-grade platinum/palladium ore. Mappings of the sulfides generated with this procedure have been quite accurate. Samples of coal have also been obtained and preliminary measurements with the imaging spectrometer have been made.
