the shaft. This will help assure that, after final closure, groundwater from this unit will be confined and not seep <br />down the inside of the shaft. <br />= Upon completion of shaft drilling and steel liner installation for both shafts, the cuttings pit will be dewatered. <br />Excess water will be hauled to the Area 1 Pit, and the remainder will be allowed to evaporate. After dewatering the <br />cuttings pit and allowing the cuttings to consolidate and dry -out, the collection pit and cutting materials will be <br />covered with stockpiled materials from the shaft collar excavation, graded and revegetated with a temporary cover. <br />A sign(s) will be posted designating the temporary mine development waste pit. The cuttings and shaft collar <br />excavation materials will be utilized to re -fill the shafts during eventual reclamation of the shaft installation. <br />As shown on Map 23, additional entries will be driven from the 18 -Left gate -road to the north to connect with the <br />two ventilation shafts. The entries will be driven in the same manner as is used in TCC's development work, i.e. <br />continuous miners and shuttle cars. <br />Following completion of shaft boring and casing operations and removal of the drilling equipment from the site, <br />emergency hoist equipment, consisting of an escape capsule, hoist derrick, hoist drive unit, control equipment and <br />18 x 24 foot pre- fabricated metal hoist house, and a pre- fabricated propane -fired shaft heater and ducting will be <br />erected/installed on the previously constructed intake shaft concrete pad. The shaft heater will be connected to a <br />propane supply tank, mounted on prefabricated concrete saddles, and a buried electrical cable. Similarly, a fan <br />enclosure (fan shroud), silencer, and electrical control building will be erected on the previously constructed <br />exhaust shaft concrete pad, and the fan, fan drive motor, and electrical control, monitoring, and communication <br />systems will be installed. It is presently anticipated that the 400 hp, 90,000 cubic -foot per minute Robinson Fan <br />and associated equipment will be relocated to the 18 -Left Ventilation Shaft from the. EMD Ventilation Shaft <br />location. A chain -link security fence with a locked gate will be constructed to enclose the intake shaft and <br />emergency hoist installation. Following commissioning, the shaft pad site and access road will be cleaned -up and <br />surface areas graded and dressed. <br />TR09 -66 2.05 — 45.61 04/07/09 <br />
