Work performed during the period 1-30 April 1977 for a Coal Mine-Coal Conversion Plant Interface Evaluation and Conceptual Design is covered. Interface conceptual engineering and cost estimating are considered. In April, conceptual designs were completed for the two ICMC coal transport alternatives, conveyors and automated rail haulage (Modules 20 and 30). The conveyor facility consists of two conveyor lines in each ICMC mine and an intermine conveyor system. In-mine conveyors feed one of two storage bunkers. A single 72-in. conveyor line transports all coal to the surface. The automated rail haulage facility transports coal between conveyor-fed train loading stations located in each mine main entry to a central unloading station. From here coal is conveyed to the surface via a single 72-in. conveyor line. The automated trains do not run to the surface because of grade limitations. A limestone handling and receiving facility was incorporated into the Coarse Coal Feed Transport Facility that provides limestone for the atmospheric pressure fluidized-bed steam/gas generators that provide steam for power generation, process steam, and hot flue gas for coal drying and pulverizing. In the steam/gas generators, the limestone removes flue gas sulfur oxides. The rail transport section of the Regional Coal Mining-Remote Conversion Site alternative was concluded. Rail haulage accounts for approximately one-thirdof the coal transportion to the remote conversion plant generic location. Several problems exist, including a reluctance on the part of railroads for intrastate hauls. Interface cost estimating was initiated during this period. Both single-capacity capital cost estimates and capital cost-capacity scale factors are being developed.
