## FG to partner with AfDB on financing of coal projects in，

Determined to solve the power issue in the country, the Federal Government is to partner with the African Development Bank (ADB) to fund coal projects in the country. The Minister of Mines and Steel Development, Dr Kayode Fayemi, disclosed this during a meeting with stakeholders in the mining sector and host communities in Enugu on Monday.30403-013: Coal Mine Methane Development Project | …,The main objective of the Project is to establish a CMM demonstration project that covers all aspects of effective and efficient CMM and CBM production, capture, and utilization by applying the latest technologies, i.e., improved CBM production from vertical surface wells and directionally drilled wells from the surface, improved CMM drainage through the use of underground directional drilling，db adb y daf en la minería de carbón - boreftvaertut.nl,DAF significa Base libre de ceniza seca (Dry Ash Free Basis) Los valores de reproducibilidad ISO para C (db) 1,00 % y GCV (db) 300J/g, convertidos a base tal cual, se usan en el cálculo de la incertidure.
