The coal seams worked in the South Yorkshire Coalfield lie mainly in the middle coal measures within what is now formally referred to as the Pennine Coal Measures Group.These are a series of mudstones, shales, sandstones, and coal seams laid down towards the end of the Carboniferous period between about 320 and 300 million years ago. The total depth of the strata is about 1.2 kilometres (0.75 mi).

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
aggregation of coal seams. A coal seam is a dark brown or black banded deposit of coal that is visible within layers of rock. These seams are located underground and can be mined using either deep mining or strip mining techniques depending on their proximity to the surface.

Abstract Formation of coal seam and coal‐rich zone is an integrated result of a series of factors in coal accumulation process. The coal accumulation system is an architectural aggregation of coal accumulation factors. It can be classified into 4 levels the global coal accumulation super‐system, the coal accumulation domain mega‐system, the coal accumulation basin system, and the coal ...
