Coal is the most highly used source of energy for generating power in the world. Although, it has adverse environmental impacts (Weart, 2003), it is so widely used mainly because it is relatively cheap, abundantly available and readily fits with traditional power generation technologies. It is extracted from mines using both underground and surface mining techniques – either of them having adva...

In multiple attribute decision making (MADM) problem, a decision maker (DM) has to choose the best alternative that satisfies the evaluation criteria among a set of candidate solutions. It is generally hard to find an alternative that meets all the criteria simultaneously, so a good compromise solution is preferred. The VIKOR method was developed for multi-criteria optimization of complex syste...

Different genetic procedures are applied to increase robustness, namely two typologies of admissible mutations for the elite subpopulation subjected to zooming and mutation and reproduction for the remaining individuals. In order to further improve convergence rate, a user-defined population percentage, depending on individuals fitness, is replaced with new phenotypes, enforcing chromosomic ren...

This article is devoted to work aimed at normalizing the condition of degraded soils in open-pit mines as a result anthropogenic influences through phytomass. By creating biological cover from plants, it has been achieved improve composition soil. Plants such Datura starmonium, Portuluca oleracea, Caspella bursa-pastoris, Chenopodium vulvaria, album, Plantago lanceolata, Vaccaria hispanica, Vic...

Determination a sequence of extracting ore is one of the most important problems in mine annual production scheduling. Production scheduling affects mining performance especially in a poly-metallic open pit mine with considering the imposed operational and physical constraints mandated by high levels of reliability in relation to the obtained actual results. One of the important operational con...

When preparing a permitted explosive recipe an energy or heat is considered, which should ensure the detonability of system and at same time power that satisfies purpose for it will be used, under conditions firedamp hazardous mines. The safety parameters charges used in mines are decisive, order to health requirements work together with efficient performance blasting operation. type emulsion r...

Open pit mine design and production scheduling deals with the quest for the most profitable mining sequence over the life of a mine. The dynamics of mining ore and waste and the spatial grade uncertainty make predictions of the optimal mining sequence a challenging task. A new optimization approach to production scheduling based on the effective management of waste mining and orebody grade unce...

The problem of annual production scheduling in surface mining consists of determining an optimal sequence of extracting the mineralized material from the ground. The main objective of the optimization process is usually to maximize the total Net Present Value of the operation. Production scheduling is typically a mixed integer programming (MIP) type problem. However, the large number of integer...

The volume analysis of open-pit mines is important for preparing the plans for environmental recultivation. To assess the predictability of finances and deadlines it is indispensable to determine the exact amount of backfilling required. A geodetic survey presupposes a very time-consuming and special expertise; furthermore, accuracy depends on the experience of the expert and on the number of c...
