Analysis of the top coal stability of the large section open-off cut under the gob in thick seams slicing mining

Abstract The reserved thickness of top coal has an important influence on the stability of a large section open-off cut under gob in the thick seams slicing mining. The destabilization extremum conditions of the open-off cut top coal were derived from by elastic–plastic theory, and the optical fibre...
