Mar 1, 2020 · The problem studied in this paper is that of designing the optimal open pit haulage ramp that, for a given ramp width and a maximum ramp gradient, connects two points of the mine, minimising construction and operational costs.

To use a ramp, the mine design must comprehen-sively take into account the mining technical con-ditions, production scale, the surroundings, and other various factors. The ramp arrangement must be optimized after detailed technical and eco-nomic comparison of the options.

timal open pit haulage ramp, for a given ramp width and a max- imum ramp gradient, which connects two points of the pit, min- imising construction and operational costs.

In this research, we made use of traffic signal lights, Radio Frequency (RF) Transmitters (Tx) and Receivers (Rx) and a traffic signal lights module to safeguard LV motion on underground ramp....

Ramps are one of the most important aspects of mine planning. Their presence should be included early in the mine planning process since they have a significant effect on the reserves (Hustrulid et al., 2013a).

ABSTRACT: The design of ramps in open pit mining is a complex problem that, even though it has a great impact in the value of a project, does not rely on optimization tools as other problems like the computation of nested pits or direct block scheduling.

In this paper, we present a methodology to assist the ramp design in underground mining, minimizing both development and operational costs. The methodology considers an optimization model that obtains an initial ramp design, which is subsequently, refined to arrive at …
