Following completion of shaft boring and casing operations and removal of the drilling equipment from the site, emergency hoist equipment, consisting of an escape capsule, hoist derrick, hoist drive unit, control equipment and 18 x 24 foot pre- fabricated metal hoist house, and a pre- fabricated propane -fired shaft heater and ducting will be erected /installed on the previously constructed intake shaft concrete pad. The shaft heater will be connected to a propane supply tank, mounted on prefabricated concrete saddles, and a buried electrical cable. Similarly, a fan enclosure (fan shroud), silencer, and electrical control building will be erected on the previously constructed exhaust shaft concrete pad, and the fan, fan drive motor, and electrical control, monitoring, and communication systems will be installed. It is presently anticipated that the 400 hp, 90,000 cubic -foot per minute Robinson Fan and associated equipment will be relocated to the 18 -Left Ventilation Shaft from the EMD Ventilation Shaft location. A chain -link security fence with a locked gate will be constructed to enclose the intake shaft and emergency hoist installation. Following commissioning, the shaft pad site and access road will be cleaned -up and surface areas graded and dressed. In order to comply with new Mine Atmosphere Control (MAC) regulations, under the jurisdiction of the Mine Safety and Health Administration (MSHA), and minimize surface disturbance, TCC will utilize the previously drilled and cased exploration borehole as a MAC borehole for nitrogen injection into abandoned mine gob areas. The 8 -inch pipe installed within the cased MAC borehole, will be used as a nitrogen injection borehole, connecting to one or more manifolded pipe systems underground, which will connect to sealed gob areas. At the surface, an 8 -foot diameter culvert manhole may be installed around the cased MAC borehole(s) as a well -head, with appropriate grounding and lightning protection to meet MSHA requirements. The fixed pipeline(s) will connect at the surface to a portable skid - mounted nitrogen generator. Associated equipment will include skid - mounted compressors, and control equipment, which will be housed in the Fan Mechanical Building. Required power for this installation will be provided by dropline from the existing substation. Installation details are shown by the design drawings in Exhibit 49R. 5. Type of vehicles used for project. During construction of the access road and pad, typical equipment will include a road blade, compactor, loader, dozer, gravel and pickup trucks. Specialized blind drilling equipment in the form of an A -leg derrick will be used to drill the pilot hole and excavate the shaft. Supplies will be delivered by 18- wheeled vehicles. After completion, the site will be accessed by mine vehicles on a routine basis and periodically by support equipment needed for maintaining the hoist and /or elevator. A road grader will be used for road maintenance, and during the winter a a road grader and /or a snowplow with sander will be used to keep the road open for TCC traffic. 6. Number of employees. The mine is an existing underground coal operation. The hourly workforce has recently been increased to approximately 600 hourly and staff persons. No additional changes, other than maintaining the existing work force numbers are anticipated at this time. 7. Phasing plan.. I I The access road for the 18 Right Bleeder Shaft is anticipated to begin in early May 2009, and be completed by late May /early June 2009. Construction of the pad will commence immediately upon completion of the access road. The preparation for the drilling of the shafts will commence in June 2009. Drilling and lining of the two shafts will take approximately 7 months to complete.
