Reasons for choosing the hammer coal crusher 1.COAL PILLAR STRENGTH AND PRACTICAL COAL PILLAR,ratios (figure 3). For practical coal pillar design, exact determination of intact coal strength thus becomes unnecessary; for wide pillars, an average seam strength of 6.2 to 6.6 MPa may suffice for most U.S. bituminous coal seams. Rock partings within the coal seam, however, were found to have a
