Baranov I. Determination of parameters of the combined dumping on iron-ore careers.

The thesis is about the decision of actual scientific task of increase of efficiency of development of iron-ore deposits on the basis of determination of parameters of the combined dumping. It is grounded the evaluation criteria, which considers all factors that have an influence in determining the parameters of the combined dumping. It is developed the method of determining the location of overburden and consistency dumping of quarries in the relative evaluation of their options on the basis of the criteria. The technique allows to choose the best option locations dumps that achieves the lowest cost to perform stripping. It is founded the influence of the parameters of the relationship of external and internal dumping on economic performance indicators stripping. On this basis, it is identified the optimum parameters combination dumping that provide secure sharing of mining and dump works produced in the space career. Modeling placement of overburden dumps in the combined group pits revealed the location of the blade depending on the distance between the quarries, the ratio of overburden varieties, land price indices and their changes over time. The research allowed the application of combined dumping create and optimize traffic flows on overburden dumps that achieve the minimum cost of stripping work.Industry - mining (engineerings sciences)
