• No. 5 Portals The No. 5 portals were constructed in 1970 specifically to access the "F" coal seam. The portals consist of four (4) entries into the "F" seam outcrop. The portals were primarily used for ventilation supply and personnel transport. Presently, the portals have been temporarily sealed, partially back-filled, and no longer provide service [o the mine. No. SA Portal The SA portals and associated facilities are located in the highwall of an abandoned strip pit. There are four (4) portal entries at the No. SA portal, two are for return air, one is for intake air, and the fourth contains the conveyor belt. Main ventilation fans for the No. 5 and 6 mines are located at the two (2) return portals. One new opening to the surface is planned to improve airFlows. A shaft will be developed from the surface to the No. 5 and No. 6 mines. The shaft will be located above the existing No. SA portals within the existing sediment control system. Portal heaters may be installed on this shaft. (Note: The shaft will be reclaimed along with the No. SA portals.) For location of the ventilation fans, refer to the No. 5 Mine Plan Map (Map 23). Oil storage tanks, a rock dust tank, a supply yard, and a sediment pond are located in the No. SA portal area. Drainage and sediment control techniques are discussed later in this section. Pole Bam Historically, a pole barn was located in the No. SA supply yard and was used for equipment and materials storage. The structure has been removed from the site.
