Determination on Interlayer Separation Threshold of Complex Roof with Mechanics Properties

Abstract:

In order to determine interlayer separation threshold and separation stability of complex roof, distribution of interlayer separation was analyzed in different conditions by a contact element method based on nonlinear contact theory in ANSYS program. The conclusion was drawn that normal stress was tension stress in the center of construction surface in deep mining and it could be considered as interlayer separation threshold of complex roof.
