Longwall Top Coal Caving Introduction Underground Coal

Choosing a mining method The various methods of mining a coal seam can be classified under two headings surface mining and underground mining Surface and underground coal mining are broad activities that incorporate numerous variations in equipment and methods and the choice of which method to use in extracting a coal seam depends on many technological economic and social factors.The top coal and the immediate roof were all regarded as granular media therefore the top coal and the immediate roof did not break during the advance of the working face ② During mining operations before caving the extent of crushing of the top coal did not meet the requirement for caving the top coal block size must exceed that measured.
