New technology of replacement of mine hoist machines
MIDIEL Ltd. together with the M.M. Fedorov mine mechanics research institute and Donskoy GOK have developed a new technology of replacement of the main part of 2C6x2.8U mine hoist machine at the “Molodezhnaya” mine of Donskoy GOK.
All the necessary equipment (hydraulic stations, hydraulic jacks, self-moving carriages, beams, hoisting and lowering device, etc.) was manufactured at the Ukrainian factories on the order of MIDIEL Ltd. and was delivered to Donskoy GOK.
The new technology of replacement has allowed:
- to reduce the standstill of the skip vertical shaft in over two times,
- to fulfill the replacement without using the mechanisms of big carrying capacity available in the hoist building,
- to get the high-quality mounting of the new main part on the separate platform and the first-class piercing of brake fields by a separate drive,
- to pay back the cost of the equipment purchased for replacement due to a short-term standstill of the skip vertical shaft.
