The additional area is required <br />in order to allow modification to the mine layout, and contain <br />subsidence affected areas within the permit area, based on the <br />accepted angle of draw for this mine. <br />Based on a review of the revised maps and supporting permit <br />documents, there do not appear to be any geotechnical concerns <br />specifically related to this proposed revision. <br />
