• Mining panels will be developed blocks of coal which can be mined by <br />room and pillar techniques utilizing conventional equipment. The panels <br />are located adjacent to the main entries and oriented perpendicular or <br />parallel to the mine property boundaries. Before mining can begin, the <br />mining panel must be completely developed on each side by panel and <br />bleeder entries. <br />The projected dimensions of the mining panels will vary. Economic and <br />physical considerations have determined the orientation of the proposed <br />panels. All mining panels will be recovered in a retreating fashion <br />once they are developed. Panels will be mined in sequence as designated <br />on the Mine Plan Map (Map 8). <br />Barrier pillars are blocks of coal which are deliberately not extracted <br />during the mining process in order to provide protection or support to <br />the mine entries or reserves. Mine Plan includes several barrier pillar <br />types. They are as follows: <br />• Main Entry Barrier Pillars. These main barrier pillars will be located <br />on each side of the main entries to provide the necessary support to <br />keep the main entries open for the life of the operation. <br />Fire Protection Pillars. Afire protection pillar will be left as shown <br />on the Mine Plan Map (Map 8), to provide support to recover the panel <br />pillars and to act as a partition in separating mine panels. This <br />partition will act to prevent containment of intake air and will also <br />serve as a firewall in case a panel were to catch fire. <br />The drift portals of the Peacock Coal Mine will be located at the <br />outcrop of the A Coal Seam. Each set of portals will have an equipment <br />roadway, an intake entry, a belt entry, and a return entry. During the <br />continued development of the operation, these return portal entries will <br />host an operating fan for mine ventilation. <br />C~ <br />2.05-5 <br />
