The present paper discusses the effects of small plants on the dump mass reinforcement and slope stability. The roots of smaller plants (such as grasses and shrubs) do not go deep. However, they stabilize the slope by binding the upper layer of dump

The smooth convex generalized failure function, which represents 1/6 part of envelope in the deviatoric plane, is proposed. The proposed function relies on four shape parameters (Ls, a, b and c), in which two parameters (a and b) are dependent on the

The hybrid method of partial extraction from underground coal mines has been proposed for better recovery without endangering the surface features. The concept of panel stability, rather than pillar stability, has been suggested for stability analysi
