摘要
石煤是早古生代地层中的煤炭,它是由菌藻类等低等生物在浅海还原环境下形成的。安康石煤以高灰、高硫、低发热量为特点,规模小,伴生有益组分多,是安康重要的民用燃料。
Bone coal occurs in Eopaleozoic coal-bearing formation. It is formed by lower fungi such as the bacterium algae in shallow reductive environment. Bone coal in Ankang region is characterized by high ash, high sulphur and low calorific value, small in scale, and more useful accompanying components. It is the most important civil fuel in the Ankang region.
