Märksõnad:
World coal production will increase up to 2040 and world energy consumption will be very much dependent on coal. For a better planning of coal mining operations, it is essential to know the strength, cuttability and workability of coal, which are interrelated. The main objective of the book is to combine the research studies and compile the book oriented to the coal industry, research students, practicing engineers, and coal mine panning teams.
