The monitoring stations will be established over the area to be mined by <br />the Peacock Coal Mine before mining activities begin. In areas of <br />active mining, each station will be surveyed and visually examined each <br />spring and fall. Final survey will be carried out one to two years <br />after the coal has been removed beneath the monitoring station. <br />Semi-annual monitoring will he implemented in lieu of quarterly <br />monitoring because of the adverse weather conditions and accessibility <br />to the area above the coal to be mined. Reports will be supplied <br />following monitoring to the Division. <br />If the subsidence monitoring program determines that the subsidence <br />prediction was inaccurate and that material damage or diminution of <br />reasonably foreseeable use of renewable resources may occur, Sunbelt <br />will submit a subsidence control plan for approval by the Division. <br />Subsidence Survey <br />Sunbelt proposes to use a room and pillar technique at the underground <br />operation. The details of the planned mining are set forth in Section <br />2.05.3. Mining will be conducted according to the sequence graphically <br />shown on the Mine Plan Map (Map 8). <br />The geology of the area is set forth in Section 2.04.6. Site specific <br />stratigraphy is shown on the Regional Geology Map (Map 5). <br />Surface Subsidence Control Plan <br />Sunbelt does not expect any adverse effects by potential subsidence as a <br />result of the of pillar extraction upon retreat and the leaving of <br />barrier support pillars. Consequently, no measures will be taken on the <br />surface with respect to subsidence control. <br /> <br />2.05-49 <br />
