Being one of the important energy since the Industrial Revolution, coal has brought human huge fortunes, meanwhile however it has also led to the living environmental deterioration. When coal cinders, as the burning wastes of coal, are piled up randomly alongside the site, they not only occupy spare land but also release sulfur-containing gases to pollute the air.
