TECHNOLOGY OF FORMATION MAN-MADE DEPOSITS AND DETERMINATION OF LOSS IN MINING OPERATIONS USING WALKING EXCAVATOR

Majority of mines operating for decades dump their waste without regard for the potential of the waste management. When starting development of accumulated waste as man-made mineral deposits, some mining companies are faced with numerous issues connected with mining safety, optimization of process-dependent parameters, stability of mining and transportation machinery, selection of mining and loading equipment, etc. These issues should be addressed at the early stage of generation of a man-made deposit of mine waste so that its further management requires minimum expenditure. The economic efficiency evaluation should take into account both the benefit from incremental products and the reduction in expenses connected with the creation and operation of tailings ponds, waste storage, prevention or mitigation of ecological impact by mineral processing plants. The reduced content of valued components in tailings, even by hundredths of a percent, can result in the considerable effect owing to the increased production output and money saving due to reduction in cost of crushing and grinding which take 40–50% of all expenses in the traditional mineral processing. The article presents the technology of generating a man-made deposit of mine waste and its further development using a walking excavator. An empirical formula describes the face area of the walking excavator, 3D model shows the walking excavator face areas in case of different digging depths. The mathematical formula defines the loss triangle as a result of intersection of operating zones of walking excavators. The proposed technology offers a mine a new outlook for the mine waste management philosophy and will enable efficient generation and development of tailings.
