<br />ANGLE OF DRAW OBSERVATIONS <br />The subsidence monitoring results are presented in Figures 6, 7, <br />and 8. The mean angle of draw from the vertical is 15.5°, with a <br />range from 11° to 21°. These values agree closely with results <br />presented by Abel and Lee (1980, Table 3, p.7). Approximately <br />580 feet of logged core taken from above the Cameo "B" Seam had <br />the following rock type distribution: <br />9.7% Coal and Carbonaceous Shale and Siltstone <br />35.1% Sandstone <br />52.3% Siltstone <br />• 2.9% Shale <br />Separating the coal and carbonaceous rock into sandstone if clean <br />and into argillaceous if silty or honey and combining shale and <br />siltstone into argillaceous results in the following rock type <br />distribution: <br />37.1% Sandstone <br />62.9% Aroillaceous <br />This compares closely with results from Abel and Gentry (1978), who <br />reported 15.0° for 63% shale and 37% sandstone. <br />• <br />
