Depending on the spatial relation between stopes, the influencing realms due to different mining excavation may partially overlap, as would result in the interaction and superimposition of two types of mining effect.

Because of effect under combined underground and open pit mining, mechanism about superimposition of deformation and change behavior depends on respectively amount of both mining methods.

It would result in interaction and superimposition of the two kinds of mining effects.
