MODEL STRUCTURE AND PARAMETER IDENTIFICATION FOR CUTTING HORIZON PREDICTION OF SHEARER LOADERS

(STEF92 Technology, 2023-10-01, Mirjam Holm, Christian Bøhn)

To reach autonomous control with good performance in shearer operated longwall mines, control algorithms have to be adapted to the system behaviour. Thus, one of the challenging tasks in this area is the identification of the behaviour, which is declared as complex and specific to each mining area. Therefore, it is necessary to determine a suitable model that reproduces the cut behaviour of a shearer loader and can be adapted to a real mining system. This paper shows and analyses possible model structures to predi...

MODELLING OF THE CUTTING PROCESS OF UNDERGROUND COAL MINING WITH SHEARER LOADERS FOR ADAPTIVE HORIZON CONTROL

(STEF92 Technology, 2019-06-20, Mirjam Holm)

Show more

Horizon control in underground coal mining is still largely based on the knowledge and experience of a human operator, while many other operations run fully automated in mines nowadays. Several control strategies have been developed for automatic horizon control in underground coal mines, but none of them worked satisfactorily for a long distance up to now, even if the used sensors execute their intended task already and were improved continuously. However, the behaviour of the mining system itself, especially the...
