涟邵煤田测水煤系煤层灰分的构造分异

运用统计方法和耗散结构原理,对原煤灰分产率和构造分异作用的关系进行研究。煤层的剪切破裂可分为碎裂、碎粒和碎粉3个阶段,与原始结构煤灰分比较,原煤灰分在这3个阶段分别处于相等、增大和减小3种状态。原煤灰分的这种规律性变化与构造的分异作用有关。构造对煤层的分异作用实质上是构造煤从碎粒阶段的无序混杂状态到碎粉阶段煤和非煤组分重组后的新的有序状态的一种不可逆过程。 

THE STRUCTURAL DIFFERENTIATION OF THE COAL SEAM ASH IN CESHUI COAL-BEARING FORMATION IN LIANSHAO COALFIELD

The relationship between the raw coal ash content and the structural differentiation was studied by using statistics and the principles of dissipation structures. Shear repture of a seam might be divided into three phases, i. e. breaking, granulation and pulverization. Compared with the ash content of the original tectonic coal, the raw coal ash content of the three phases were respectively equal, increased and decreased. Those regular changes of raw coal ash content were related to the structural differetiation. In fact, the differentiation of coal by structures was an irreversible process of tectonic coal from a disorder status du ring the granulation phase to a new order status after recombination of coal and non coal components during the pulverization phase.
