water consumption in coal preparation

Pressures imposed by energy production on compliance with

Although poor in water resources, Northern China is richly endowed with fossil fuel resources. This geographical mismatch aggravates local water scarcity as energy production requires a significant amount of water input for coal mining in preparation for power generation (Spang et al., 2014). 70% of China''s coal mines are loed in waterscarce regions in the north and 40% of them face severe
