VG Railway implementation in NLMK company

Customer
NLMK (Stoilensky GOK)

Description

Stoilensky Mining and Enriching Plant is one of the three leading Russian enterprises for the production of iron ore. Stoilensky GOK is one of the most profitable mining companies in the world. It is a unique enterprise that combines high efficiency, low production costs and the highest quality products. High-grade ore and banded iron formations are mined using the open-pit method. High-grade ore with a high iron content (50-56%) is immediately shipped to consumers, and banded iron formations are ground up and sent to a dressing plant, where iron ore concentrate is extracted by means of magnetic separation. Railway transport and ore transhipment at railway stations are used in the process of production at the enterprise.

VG Railway (the microprocessor control system for devices of signals, centralization and interlocking) is in operation at 7 of the company's stations (Stoilensky GOK, Mikhailovsky GOK, Lebedinsky GOK, Chernigovets open-pit mine, Vostochniy open-pit mine (Kazakhstan)). A dispatching control centre has been established for the enterprise's entire system of railway transport.

Using the VG Railway the enterprise's stations are integrated into a single data-processing network. Station attendants simply observe the trains' movements without needing to manually control call signs: the routing system automatically transfers trains from section to section and from station to station through the hauls.
The company's plans for further development of the system involve automatic optimisation of cargo flows and logistics processes in rail transport.


Tasks

  • Improving the efficiency of locomotive control;
  • Creation of a central dispatch control system for all stations and the movement of trains;
  • Switch to modern microprocessor control systems for stations.

Results

The productivity of locomotives is increased due to a higher level of work organization for station duty officers, dispatchers and managers responsible for the operation of the mining and transport complex. The changes were due to:

  • Visibility of the ongoing processes and, as a result, more informed decisions in order to reduce the locomotives' downtime and downtime during loading and unloading;
  • Increased staff discipline (all actions of the participants of the transportation process are automatically displayed in real time and recorded);
  • Reducing the delay of locomotives due to faults of the signaling devices, for example, "false occupancy" of the road section.

Savings on operating costs (spare parts, materials and electricity), in particular:

  • Replacement of rail insoles (insulating rail lining) separating the rail chain into sections, for ordinary non-insulating knocking (metal lining);
  • The use of metal sleepers and, as a result, an increase in the service life of rail-sleeper gratings, a reduction in the consumption of upper track materials due to the reduction in the number of rail track repairs;
  • Energy savings in electronic system of axis accounting devices (equipment consumes less power than equipment of rail circuits).

Further development:

Automatic optimization of freight flows and logistics processes.
