of the present coal preparation plant will be increased to 600 <br /> tons per hour by the time the tunnel complex is completed . <br /> The existing mine portals and haul roads will <br /> be generally retained, but the level of activity will be greatly <br /> reduced . The various mine portals are critical to the mine <br /> ventilation system, and from time to time require some maintenance <br /> as do the main mine drifts, which are also critical to the main <br /> ventilating system. The present mine hoists and main line belts <br /> will be retained on a standby basis and will at times be used for , <br /> inspections and mine maintenance work. As the several mines are <br /> connected with the rock tunnel, the status of the road to the <br /> particular mine will change from a main haul-road -category to a <br /> service category. Change in road usage from main line haul road <br /> to service road will reduce the environmental impact of the road <br /> and will in some instances allow partial reclamation of the road . <br /> The rock tunnel project is scheduled to be <br /> completed in 1987 with partial operations from the B Bed (No . 1 <br /> Mine) to commence about the middle of 1986 . <br /> (3) Environmental considerations <br /> During the five-year term of the initial <br /> permit, construction of the rock tunnel will disturb approximately <br /> 32 acres of ground . The approximate acreage of the disturbed <br /> areas is as follows: <br /> 6 .4 acres - A portal and yard area; <br /> 4 . 0 acres - Water control facilities; <br /> 13 .4 acres - Tunnel spoil disposal area; <br /> 8 . 1 acres - A belt conveyor to preparation plant <br /> and raw coal storage. <br /> 31 . 9 Total <br />
