In the southeastern Serbia, in the area of the municipality Bor, there are three flotation tailing dumps: FTD Bor, FTD RTH (the ore body H) and FTD Veliki Krivelj. The Flotation Tailing Dump Bor is abandoned, partly reclamated. The other two are active flotation tailing dumps. All three flotation tailing dumps are serious polluters of air, water and soil. The affected zones by dust from these tailing dumps threat large areas in a direction of dominant wind from the northwest direction. The affected areas by the impact zone of dust from: the Bor Flotation Tailing Dump amount to 18,361,074 m 2 , flotation tailing dump of the ore body H, 3,713,408 m 2 and Flotation Tailings Dump Veliki Krivelj, 16,077,805 m 2. The most effective measure against dust rising from dry areas by the wind is the use of reclamation with the phases of technical, agrotechnical and biological reclamation.

In the open pit mining of mineral raw materials, blasting, whose role is to break the undisturbed mass for easier loading, is the necessary technological phase. In the mass blasting at the open pits of metal ore, there is a rise of cloud composed of gases and dust, blasting mining products, which have negative effects on the surrounding environment. This work presents the calculations of a cloud size, concentration of gases and dust in blasting.

The existing landfill at the site "Maljevac" is still active and should provide the additional space for ash and slag disposal in the following period. For these purposes, the stability analysis of the existing landfill condition, as well as the stability calculation for overtop the landfill to the peak elevation K +832 m were carried out. The stability by analytical profiles was calculated by the licensed SLIDE v6.0 software.

The world mining companies for design of mining facilities and with the aim of rational and cost

The development of mining operations at the South Mining District Open Pit of the Copper Mine Majdanpek is conditioned in the following short term by removal the accumulated water, sludge and sediment from the inactive water collector from the level +150 m to the bottom of the Open Pit at +122 m. This must be done in order to create the conditions for the smooth development of the ore mining operations. This paper presents the technology of pumping the clean water.
