1. 1. Haulage system optimization for underground mines : A discrete event simulation and mixed integer programming approach

   Författare :Abubakary Salama; Jazek Paraszczak; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mining and Rock Engineering; Gruv- och berganläggningsteknik;

   Sammanfattning : In coming decades, many underground mines will operate at greater depths, which will affect many operational factors such as increased rock stress, longer haulage distances, and higher energy consumption, which potentially can generate lower production rates. The increased rock stresses may lead to smaller sized openings, further restricting the size of loading and hauling equipment that can be used. LÄS MER

3. 2. Optimization using discrete event simulation and mixed integer programming: application on haulage systems for deep underground mines

   Författare :Abubakary Salama; Sunniva Haugen; Luleå tekniska universitet; []

   Sammanfattning : The application of discrete event simulation for the optimization of the haulage methods of underground operations at great depth is presented. The discrete event simulation was carried out to evaluate four haulage methods for the improvement of the overall mine production and a minimizing of the operating costs. LÄS MER
