一、石煤的成因及储量分布石煤是贮藏在古老地层中的一种可燃物质,它是在浅海环境条件下由藻类、菌类等低级生物形成的。含石煤的地层是由一系列沉积岩所组成。煤岩类型属高变质的腐泥无烟煤,但其变质阶段一般高于无烟煤。它由有机质和无机质两部分组成。有机质占10～15％,主要是由低等生物转化而来,是 First, the origin and reserves of stone coal stone coal is stored in the ancient strata of a combustible material, it is in the shallow sea environmental conditions by the algae, fungi and other low-level organisms formed. Stones containing stone coal is composed of a series of sedimentary rocks. Coal type is a highly metamorphic sapropelite anthracite, but the metamorphism stage is generally higher than anthracite. It consists of organic matter and inorganic two parts. Organic matter accounts for 10 ~ 15%, mainly from lower organisms transformed, is
