Drilling rigs of domestic production entered into Gaysky GOK
Gai (Orenburg Region)
The underground mine of Gaysky GOK (an enterprise of the UMMC raw materials complex) received DF-B1 underground hydroperforating drilling rigs manufactured by Machine-Building Holding JSC (Yekaterinburg). Currently, five drilling rigs are operating underground: three in an underground mine and two in a mine construction department. The electro-hydraulic drilling rig is designed for driving workings and tunnels with a cross section of up to 40 m 2 .
The drilling rig is serviced by two people - a tunnel driver and his assistant.
" The machine performed well. The same automatic control, and in some ways even better than the imported ones, on which I had worked before. For example, we see on the control pad not just a light-up sensor - an "error", but what exactly has failed, ”says Evgeny Samokhin, a drifter of the underground section of mining and tunneling works No. 16. - There were initially concerns about the technology - after all, we have only a few domestic-made drilling rigs, but they were dispelled in the process of work. The main thing is that the installation fulfills the specified volumes. ”
“ We received the first machine last year, and within six months it passed our industrial test. All this time, representatives of the plant worked closely with us, they watched how the installation behaves in operation, they were very attentive to our comments, suggestions and, accordingly, later on at the plant, the machine was being finalized. And now we have service engineers who very quickly respond to questions that arise. And, which is also important, the new equipment did not require long periods of personnel training, ”says Dmitry Nesterenko, head of the plant's underground mine.
Note that in 2021 UMMC plans to allocate more than two billion rubles for the acquisition of a mining equipment for replacement and modernization of equipment worn out and not included in the estimate of construction projects for PJSC "Gaysky GOK" (an enterprise of the raw materials complex of UMMC).
