5 Steps of Technical procedure

Project idea

Project development

Legal approval

Project installation

Project operation


Project idea - Technical procedure for porject design and construction

After the idea for the project was created, the technical conditions have to be checked at the mine. Special feature have to be observed:

- CMM Quality

differend sources of extracted gas produce CMM with differend methane content. The quality of CMM is an important fact for the kind of utilisation.


- Amount of CMM

The amount of CMM is mainly determined by the gas content of the coal deposit and the dimension of mining.The gas content of coal seams are different. Therefore, the gas released amount varies depending on the mined coal seam. This fact is one of the important date for the capacity


- Availability of CMM

Coal seams are also present, which contain only little gas, so the degassing system can be switched off completely during this mining time. All release methane is transported by teh ventilation air to the atmosphare.


- Existing extraction systems

- Any demand for electricity and heat on the mine

- surplus methane (The surplus of CMM can be burned without energy recovery to reduce greenhouse gas emissions)

Project development - organisation of the project conditions

- Installation place

After clarification of the project idea a place for the installation as to be found. The owner of the ground and the facilities in the surroundness have to accept the location. In some cases you have to take care of the noise production and the air pollution.


- Connection for feeding and products

The connection to the gas extraction point as be planned. Often there are special safety instruction to this connection. A controling for methane concentration is necessary to insure that only CMM with concentration higher than 25 % is routed to the utilisation.

The products heat and power must be feeded to the local grid. So the technical conditions mus be coordinated.


- Rules of project partners

Within the project are several partners. The project coordinator has to ensure all partners understand the project and know enough about the project.


- Financing

In this status of the project the financial Requirements should be known. The time schedule for the payment must be set up and the financial planning must include this project.
