无产阶级文化大革命以来,为了落实毛主席关于“开发矿业”的伟大号召,我省广泛地开采和利用了石煤资源。当前,石煤不仅用于生活上,而且用于工业生产上,特别是用于烧石灰、烧砖瓦等过去大量消耗原煤的行业。石煤是一种低碳低热值的燃料,发热量约在600～1200大卡/公斤,固定碳含量一般在10～20%左右,含硫量在1.8～ Since the great proletarian cultural revolution, in order to implement Chairman Mao’s great call for “developing mining”, our province has extensively exploited and utilized stone coal resources. At present, stone coal is not only used for life, but also for industrial production, especially for industries such as burning lime, burning tiles and bricks, which used to consume large amounts of raw coal in the past.
