Energy consumption structure for, current coal occupies 70% or so, is the national main energy sources depended on for existence.
According to the difference of structure and composition, coal is divided into lignite, bituminous coal and anthracite three major types, its metabituminous coal
It is divided into lower-grade metamorphic bituminous and mesometamorphism bituminous coal again, lower-grade metamorphic bituminous also referred to as ub-bituminous coal, itself and lignite one
Rise and be referred to as " low-order coal ".According to statistics, the reserves of China's low-order coal account for national explored coal reserves
More than 55%, up to 561,200,000,000 tons, but because low-order coal is used as the product at incoalation initial stage,
With phosphorus content it is low, moisture is high, easy efflorescence, easy spontaneous combustion, fugitive constituent high, immersion intensity difference, anti-dropping
