UTILIZATION OF COAL MINE METHANE

"Coal Mine named after AF Zasyadko" (2010)

The purpose of the project was to develop a comprehensive degassing system at the Zasyadko mine, in accordance with the provisions of the Comprehensive Program. The project aimed to reduce methane emissions and enhance safety by drilling underground wells and introducing vacuum pumping stations (VPS) at three key production sites: Vostochnaya, Yakovlevskaya, and Grigorievskaya.

Installation of PowerLink GXE250-NG Gas Engine

A PowerLink GXE250-NG gas engine was installed as part of the project, providing a reliable power source for the degassing operations.

Drilling Operations

The project involved the operation of 11 drilling rigs. These rigs were used to drill extensive networks of underground wells, with 10-12 km of degassing wells drilled each month to enhance methane capture.

Degassing Pipelines

A total of 42 km of degassing pipelines with diameters of 630 mm and 530 mm were laid to transport the captured methane from the wells to the vacuum pumping stations.

Vacuum Pumping Stations

Three vacuum pumping stations were installed and put into operation:

  • Two stations at the Vostochnaya production site, each equipped with 6 vacuum pumps (12 pumps in total).
  • One station at the Yakovlevskaya production site with 9 vacuum pumps.

A fourth vacuum pumping station was commissioned at the Grigorievskaya production site, consisting of 9 vacuum pumps, each with a capacity of 150 m³/min.

Methane Capture and Utilization

The project achieved a daily flow rate of 150 m³/min of captured methane. As the degassing activities developed, the rate of captured methane increased to 500 m³/min, significantly enhancing the effectiveness of methane mitigation efforts.

Environmental Impact

The successful implementation of the degassing project resulted in the reduction of methane emissions, leading to the issuance of 4,386,419 European Reduction Units (ERUs). This achievement underscored the project’s contribution to environmental sustainability and compliance with international emissions reduction standards.
