Economic System Analysis of Coal Preconversion Technology:Phase I. Volume VI. Computer Systems to Support Mine Planning. Interim Report for the Period August 1973--July 1975.

摘要

This volume discusses the computer work done to support the studies reported in the other volumes of the series. Data files,data file maintenance programs,and mine planning simulation models developed during Phase I are described in this volume. The simulation models were designed specifically for planning unit operations within the mining complex,and for providing general information to use in developing macro models. The model descriptions are in the form of ''User's Manuals.''The models cover the following unit operations:land clearing;drilling and blasting;area stripping with draglines;coal loading with shovels and front-end loaders;coal hauling with off-highway trucks;and hauling with belt conveyors. The data files were set up to support the model development effort. These files include information on geology;geography;coal resources and reserves;mining equipment;population statistics;weather statistics;and industry financial statistics. The geology,geography,and resource and reserve files cover only regions of interest for large-scale surface coal mining. The data file discussions illustrate the data content but do not include detailed descriptions of file structures. Example listings of data from the files are included. This document does not include copies of the data files,and it does not cover case studies made with the models. The data files and case studies will be published in separate research reports,as appropriate. (ERA citation 01:019571)
