The pore capacity is becoming smaller with increasingthe vitrinite content. 2. Micro-porosity is dominated in the total pore capacity, which takes more than50%. There is not relationship among pore capacity and specific surface with otherfactors such as Maceral and R0, which shows that the distribution and shapes of poreare not influenced by the composition of the coal. 3. The pore is opened for the coal of Ordos Basin, the order is from durain to clarainthen samples to vitrain. Others are belong to half-opened and thin throat. 4. The adsorption content of gas is increasing with the higher pressure, and the freegas content is decreasing;The adsorption content of gas is decreasing with thehigher temp, and the free gas content is increasing;The adsorption content of gas isincreasing with higher vitrinite content for the kennel coal when temp.
总空隙主要由小孔孔容构成,小孔孔容占了50%以上;镜质组含量和惰性组含量等物质以及镜煤反射率均与孔容、比表面未表现出明显的相关性,说明孔隙分布特征不受物质组成的影响 3、鄂尔多斯地区的空隙呈现开放状态为主,空隙开放的次序为暗煤-亮煤-煤样-镜煤,其他盆地则为半封闭和细瓶颈空隙 4、随压力增加,煤对气体的吸附量增加,煤中所含游离气的量随之减小;随温度增加,煤对气体的吸附量减小,而煤中所含游离气的量随之增加;在相同的温压条件下,同是长焰煤的样品,吸附量在孔容中所占的比例随镜质组含量增加而增加。
