THE FEATURES OF ENCLOSING ROCK MASS DISPLACEMENT IN THE PROCESS OF COAL LAYER DEVELOPMENT
Keywords:
rock mass, rocks displacement, minedout spaceAbstract
Results of researches on equivalent materials models of rock mass displacement over mined-out
space in the zone of removal works influence are
cited. The influence of bending lines slope angles
and layers collapse on formation rock mass displacement area is determined also. The calculation method of determination primary step rocks
collapse over mined-out area is offered.
