@article{osti_6320285, title = {Coal mining technology: theory and practice}, author = {Stefanko, R}, abstractNote = {This book is intended for use in teaching coal-mine design to undergraduate mining engineering students. The preliminary chapters cover the geology of coal, coal statistics (classification, distribution, resources etc.), exploration and mine planning and development.
Technology for mining thin coal seams (less than 1 meter thick), particularly thin-seam longwall technology, would be beneficial. In view of the extreme difficulties for workers in such a constricted environment the technology for thin-seam longwalls must include as much automation, remote control, and autonomous operation as possible.
Modern technology in coal mining increases the safety of workers and enables mine planners to map mines efficiently, monitor orebodies, and track output volumes and productivity more accurately. Dragline operators, for instance, use an in-cab display which provides extensive technological information.
