Research of land-saving schemes of mining the horizontal sedimentary mineral deposits

Abstract

Technological mining transport schemes of open development of horizontal sedimentary deposits are considered. Various land-saving technological schemes for transportation of minerals in the absence of a capital trench have been developed. The dependence of the mineral transportation cost on the production capacity of the mine for the developed schemes was established. The research has been carried out for conditions of surface mining manganese deposits of Nikopol Basin. Transport schemes using mobile steeply inclined conveyor are offered. The developed technological solutions for the conditions of surface mining of deposits of the Nikopol manganese ore basin allow not only to reduce the amount of disturbed land, but also to reduce the cost of minerals by reducing its transportation distance by 2 km. The proposed transport schemes will make it possible to obtain an economic effect in the amount of 1–3 million UAH.
