Environmental Inpact of Open PIT Mining: Case of

2020-8-19  During the operation stage the noise level in the overburden dump sites can be minimized by the following methods: 1. Minimize the haul road gradient in the dump as far as possible. Since the noise level of the dumper depends upon the power required by the engine. Lower the gradient of the haul road, lower the power needed and hence the noise level can be minimized to some extent. 2. Reduce the overburden material falling during the dumping

Optimized open pit mine design, pushbacks and the gap

2014-12-4  Existing methods of pushback (phase) design are reviewed in the context of “gap” problems, a term used to describe inconsistent sizes between successive pushbacks. Such gap problems lead to suboptimal open pit mining designs in terms of maximizing net present value. Methods such as the Lerchs-Grossman algorithm, network flow techniques, the fundamental tree algorithm, and Seymour’s
