    • An experimental study of the agglomeration of coal

    2018-1-1  The Taiyuan formation (Upper Carboniferous) and Shanxi formation (Lower Permian) are also main coal-bearing strata, with approximately 17 coal seams in this area (Fig. 2b). The total thickness of the coal seams is approximately 30.74 m, and the No. 3 coal seam has an average thickness of 9.7 m.

    2015-3-1  Takanohashi et al. 30., 31. prepared coal samples with different aggregation states by extracting Argonne premium coal with a solvent composed of carbon disulfide, N-methyl-2-pyrrolidinone (CS 2 –NMP), acetone, and pyridine. They found that the adsorption capacity of the solvent-extracted coal was enhanced due to newly developed pores in these less aggregated structures.

    2018-9-1  Geometrical characteristics of fold structures in coal seams and changes of coal thickness were analysed, based on comprehensive evaluation indexes, such as the length–width ratio of folds, interlimb angle, ratio P1 of projected width of fold limbs to that of the hinge zone, curvature ratio P2, the maximum curvature and amplitude. The statistical analysis of the four coal mines shows that the

    2002-4-1  It is believed that the transgression events controlled the aggregation of coal in epicontinental sea basin, the rising of the base level provided favorable condition for the growth of peat swamp, while the large scale of transgression later on stopped the peat accumulation, which put the peat in a deoxidizing environment for a relatively short time for being preserved to form coal, and makes it impossible for very thick coal seams to be formed in such short period of peat

    2018-2-17  the coal reservoir, the pulverized coal output is common during drainage (Li et al., 2010; Liu et al., 2011). Pulverized coal that sticks in the natural fractures or pores can reduce the permeability of the coal seam and disrupt the normal production so that the coalbed methane well decays prematurely. The aggregation of pulverized coal in the
