Improved sensing for a mining machine and method

摘要

This invention relates to a mining machine including an extraction device, an at least 2D co ordinate position determining device for generating a future path according to an intended cut profile based on the determined current absolute co-ordinate position of the mining machine as distinct from an expected co-ordinate position; and for generating a seam model of the seam to be cut and/or a cut model of the seam that has been cut. The mining machine further includes sensors to collect characterising data of the seam, said characterising data forming part of the seam model and/or cut model and includes a processor to generate the seam and/or cut model and to control parameters of said mining machine. The processor analyses data from the sensors to determine sensor inaccuracy and/or imprecision, and in its absence, controls the parameters of said mining machine based on the model to anticipate changes in mining conditions.
