The Factory of the modular degassing units

LLC “RDE “Factory of MDU” was founded in  2009 according to initiative of leader Kuzbass mining coal enterprises as manufacturer factory of modular degassing units.

The basic direction of LLC “RDE “Factory of MDU” is production of the equipment for preliminary degassing of developed coal layers, degassing of adjacent coal layers and pumping of concentrated methane-air mixtures from worked-out areas. The units of the type MDU with an automated control system, meet all requirements of “Instructions for the degassing of coal mines”, “Instructions for use schemes of airing of excavation areas of mines with isolated removal of methane from out space using gas-suction units”.

For the last four years the units of type MDU have been put in operation at such coal enterprises as “”Belon”, “Sibuglemet”, “SUEK-Kuzbass”, “Yuzhkuzbassugol”, “Severniy Kuzbass” and many others.

There are innovative technologies  and  the highest quality components in the units, produced by LLC “RDE “Factory of MDU” which are based on  rotation and liquid ring pumps of Italian factory ROBUSCHI (GardnerDenverS.r.l.–Divisione ROBUSCHI) production.

  • The plant is located on the territory of  Kemerovo  region. The total area of the enterprise is over 15000 м^2, the number of highly qualified specialists is more than 180 people.
  • The factory produces modular degassing  units of  two types:
    • on the basis of rotary pumps;
    • on the basis of liquid- ring pumps.
  • The factory executes installation and the equipment commissioning.
  • The factory executes a full instructing and training of the personnel of the companies-customers (specialists attend the factory of the company ROBUSCHI,  Parma, (Italy).
  • The factory produces cogeneration units (energy and heat generation from the extracted coal mine methane) in cooperation with company TEDOM a.s., (Czech Republic).
  • The factory executes a full instructing and training of the personnel of the companies-customers (specialists attend the factory of the company TEDOM a.s, (Czech Republic).
  • The factory produces high-temperature flare units of closed type with the possibility of subsequent using of heat.
  • The factory manufactures thin-walled degassing pipes in diameter from 300 to 1500 mm.
  • The factory produces a full range of works on drilling of degasification wells, including:
    • The drilling of degasification wells;
    • The sealing of degasification wells;
    • The installation of degasification pipeline and connecting it to the modular degassing  units.
  • The factory provides continuous monitoring of gas environment parameters (the concentration of methane, carbon oxide, oxygen, the negative pressure in the pipeline, flow rate and temperature of methane-air mixture in all the way of its passage from a borehole (underground degassing network) to vacuum-pump station.
  • The factory provides service maintenance, warranty and post-warranty repair of the supplied equipment.
  • The factory produces metal constructions and containers for technological equipment.
  • The Construction work on the surface for the unit of the MDU are produced in cooperation with LLC  "Yuzhstroy-Group",  (Certificate No. 0752.01-2014-0411167670-C-223, No. SRO-P-142-27022010-0411167670-274).


Units of the type MDU are  developed with the participation of the Institute of Comprehensive Exploitation of Mineral Resources Russian Academy of Sciences (SCIENTIFIC STATION, RAS), and with the involvement of technical experts from the leading coal companies of Russia.

Modular degassing units meet all the requirements of "Instructions for the degassing of coal mines" and "Instructions for use schemes of airing of excavation sites of mines with isolated removal of methane from out space with  gas-suction  units".

Thus the units of the  type MDU are adapted for the using in the coal mining industry of the Russian Federation. They are used in mines, where it is impossible to ensure the content of methane in the air within safety standards by means of ventilation.

Constructive reliability and safety

High-quality materials and certified equipment are used in the production of units. Electrical equipment in explosion-proof version is installed in the technological modules. In addition, all the sensors that installed in the modules of degassing and purification, have explosion-proof and included in the State register of approved measuring instruments of Russia.

The construction of the unit provides for location of pumps as in the same or in different modules. In case of emergency situation it allows to stop the pumps located in one module, while they will continue to work in another one. Thus, the degassing process will not stop.

In all technology compartments there is control of atmospheric composition and in the case of appearance of methane in dangerous concentrations, all electrical equipment turns off.

The units of the type MDU have the certificate of the technical regulations of the Customs Union "On safety of equipment for explosive environments" (TR CU 012/2011), and permission for using by the Federal environmental, industrial and nuclear supervision service of Russia.

Automated control system

MDU are equipped with an automated control system (ACS), which provides control of parameters of degassing unit work, displaying the current status of the units and  technological processes on the screen of the operator panel, operation via operator panel, and  archiving of information about the MDU units state and the values of the controlled parameters of technological processes, and its output to the screen of the operator panel in the form of graphs.

ACS allows to control the degassing unit by manual (local) and automatic modes. In the first case, management by mechanisms is implemented by the operator screen of operator station.  In the second - by programmable controller according to a given program without operator intervention.
