Maximum height estimation for mine waste dumps

Waste dumps are widely used to discharge stripped mine wastes in open pit mining methods. As progresses, the height of waste will increase gradually, which may induce sliding failure once exceeds a critical value. Therefore, estimation maximum dumping is crucial life-cycle use dump. However, published information about extremely rare. In this study, estimated based on strength-reduction technique by numerical simulations. The influences dump geometry and properties investigated. results show that decreases as slope inclination angle or unit weight materials y increases, but when shear parameters (cohesion c internal friction 9) increase. starts with ground p occurs at interface between base. Furthermore effects width B, Young's modulus E, Poisson's ratio u almost insignificant. Good agreement was found available literature those obtained study.
