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)
