Original Application <br />• Page 3 <br />COMMENTS <br />Discussed angle of draw, written in <br />response to questions on subsidence on <br />lands adjacent to the Tatum's. <br />Discusses that 1 North was shut down <br />and sealed because of soft floor and <br />flooding. <br />Information on geology, information on <br />hydrology, studied subsidence <br />characteristics during early phase of <br />mining a longwall panel and a room and <br />pillar panel, no retreat, same extraction <br />as in 1N the mine section near the <br />Tatum house, Subsidence effects <br />recognized over both panels. Allen Mine <br />studied now the Golden Eagle Mine. <br />Notes that the Profile Function Method <br />is to be used for transverse analysis. The <br />Tatum house is longitudinal to the <br />underground mine. The Influence <br />Function Method is the correct <br />formulation. Profile Function Method <br />used in initial evaluation by OSM. <br />Method also allows use of empirical data <br />for analysis. Data obtained from <br />Woodward -Clyde Report. <br />Information on Geology, Soils, <br />Hydrology, structures, incomplete data <br />on subsidence. Includes maps and <br />narrative. <br />
