煤炭是人类历史上最古老的能源之一,在很早以前人们就把它称誉为“黑色的金子”;到了近代,人们又称它为“工业的粮食”。从历史上看,煤炭与人类文明的发展是息息相关的。到目前为止,已探明的全球煤炭储量约为1万多亿吨,我国约占其中的15%。在世界一次能源结构中,目前煤炭所占的比重仍然在25%左右,仅次于石油而居第二位。 Coal was one of the oldest energy sources in mankind’s history. People long ago praised it as “black gold.” In modern times, people called it “the grain of industry.” Historically, the development of coal and human civilization is closely linked. So far, the proven global coal reserves have reached about 1 trillion tons, and China accounts for about 15% of the total. In the world primary energy structure, the proportion of coal is still about 25%, second only to oil.
