Japan to curb coal

Jul 13, 2020Coal's share was around 23% before the Fukushima nuclear disaster in 2011 and rose to 31% by 2015 to make up for shuttered nuclear plants. Japan plans to cut the share of coal-fired capacity to 26% by 2030. SP Global Platts Analytics estimates 7.5 GW of coal-fired capacity in Japan will come online between 2020 and 2024.

Coupling Relation between the Location of Cross

Injecting nitrogen into goaf has been widely adopted for preventing fire hazards in coal mines. In this paper, the coupling relation between different locations of negative pressure of cross-cut drainage and nitrogen injection was investigated. The minefield data collection was carried out by an in situ beam tube system on the intake airway and return airway of the mine goaf.
