PROJECT ESSENCE
At present, the depth of a number of quarries in Kryvbas is more than 400 m. This leads to an increase in the share of transportation to 50-70% of the total cost of production, environmental pollution and a significant increase in the cost of iron ore production. It is proposed to solve the transport problem by developing of new design solutions for reloading installations of combined modes of transport, taking into account the specifics of mining equipment at great depths. The technological solution is to introduce new elements to the complex (self-propelled trucks, inclined part of the reversible loader, car stele, stacker), which allows continuous handling work in a given mode of transportation of rocks with increased labor productivity and reduced costs.
APPLICATION FIELD
The developed technological solution can be used at mining and processing plants. There are following potential consumers of developed design solutions in Ukraine: Metinvest (PJSC Inguletsk concentration plant, PJSC Pivnichnyi concentration plant, Tsentralnyi concentration plant), JSC Pivdennyi concentration plant, ArcelorMittal Kryvyi Rih (open mine No 3), as well as research and design organizations.
ECONOMICAL EFFECT
The introduction into production of an installation for reloading rocks from the conveyor to the railway transport will allow to obtain an annual economic effect of 190-450 million UAH, and installations for the completion of reserves under the entire railway - 100-125 million UAH annually.
INTELLECTUAL PROPERTY RIGHT
Patent of Ukraine for the invention No 101246 "Complex for loading the belt conveyor" dated 11.03.2013.
