Purpose. Development of the process scheme of mining-hauling operations at the mining flooded deposits. Methodology. The choice of rational haulage equipment according to the conditions of mining flooded Motronivskyi placer deposit is performed by using the analytical method of research. The graphic-analytical method of research was used in developing the recommended technological schemes of mining-hauling operations using conveyor haulage. For substantiation of technological schemes parameters of overburden transportation, the method of technical and analytical analysis was used. findings. The world experience in the mining titanium deposits is summarized and the main benefits of underwater mining at Motronivskyi placer deposit are highlighted. The analysis of traditional methods and equipment for overburden rocks transportation to this pit condition was carried out and a new design of a belt conveyor with a rope and mining technology is proposed. The basic indexes of economic efficiency of the developed technology are defined: decreasing operating costs while reducing transportation distance, the net present value (NPV) and internal rate of return (IRR) were estimated. Originality. The obtained research results of determining the impact of changing parameters and equipment in technological mining scheme of Motronivskyi watered alluvial placer deposit using the proposed systems of continuous mining for the overburden remove on the net present value of the project allowed determining the Internal rate of return and payback period. Practical value. Technological solutions for the introduction the connecting conveyor with a rope in the pit field centre in the technological scheme of transporting overburden rocks are justified. The use of floating support on the pontoon allows stabilizing the conveyor belt in a surface part of the deposit. Maintenance of the conveyor elements is significantly simplified and facilitated improving, as a result, work safety and its efficiency. keywords: open-cast mine, titanium deposits, flooded deposit, overburden, haulage, conveyor belt, rope
