WAYS OF IMPROVING OPERATIONAL INTEGRITY OF FOREIGN UNDERGROUND SELF-PROPELLED MACHINES IN URANIUM MINES IN RUSSIA
The article describes operation of Sandvik service center of foreign load-haul-dumpers (LHD). Causes of breakdowns of foreign self-propelled machines are presented. Basic methods of accumulating data on reliability of mining machines in a mine were chronometration, recording and record keeping of operating time between breakdowns and the breakdown elimination time in the machine maintenance-and-running log: data on factual consumption of spare parts; data on LHD breakdowns and downtime durations obtained from attending personnel. The most credible information fed by the chronometration was used to derive actual reliability indexes, considering conditions of operation, maintenance and repair of underground self-propelled machines.
The analysis of operation of foreign mining machines has resulted in a package of administrative and technical measures toward higher reliability of self-propelled machines in operation in uranium mines of Priargunsky Industrial Mining and Chemical Union.
Implementation of the administrative and technical measures will ensure the required reliability of mining machines at operation stage.
Key words: load-haul-dumper, service center, reliability, repair, downtime.
