• <br />2.05.6(6) <br />adequate to measure subsidence in concurrent and real time with the mining. <br />The detailed seismic monitoring program is explained in Volume IIIA, Exhibit <br />18 with specific emphasis on the quarterly seismic monitoring reports. The <br />detailed monitoring program for the Bruce Park landslide is presented in <br />Exhibit 20. <br /> <br />(d)(i) A subsidence control plan per Rule 2.05.6(6)(f) for the Bruce Park Dams and <br />landslide is included in the permit application as a contingency plan in case <br />the subsidence, seismic and slide monitoring programs show that material <br />damage to the dam and/or landslide is occurring or is going to occur. <br />(e) Not applicable. <br />(e)(F)(IV) Not applicable. <br />(f) A description of the subsidence control plan, prepared by appropriately <br />qualified professionals follows: <br />(f)(i) A description of the physical conditions, such as depth of cover, seam <br />thickness, and lithology, which affect the likelihood or extent of subsidence is <br />presented in Volume IIIA, Exhibit 15, 17 and 21. The depth of cover data is <br />presented on Map 27, Subsidence. <br />(f)(ii) A narrative of the detailed description of the mining method and other <br />measures to be taken which may affect subsidence follows: <br />(f)(ii)(A) Room and pillar and longwall mining will be used for coal removal. The size <br />sequence and timing for development is presented on Map 14 and 14B, Mine <br />Plan. <br />(f)(ii)(B) Nearly all of the areas to be mined are areas in which planned-subsidence <br />mining methods will be used. There are a few exceptions to this statement <br />as outlined below. <br />In order to protect against chimney subsidence, only development mining will <br />be performed in areas with less than 110 feet of overburden. <br />• <br />PR-11 <br />I z~ 19~a ~ <br />2.05 - 110 - 11 /08 <br />
