Use of computers in the coal industry 1990, proceedings of the fourth conference, held West Virginia University, Morgantown, 20-22 June 1990.

The papers are presented in eight sessions: Mine automation, which includes papers on real-time control systems, neural network navigation and utilisation of mechanical linear transducers; Application of geostatistical methods in coal preparation and quality control I (2 papers); Ground control I, which includes papers on using CISPM in subsidence research and control, using AutoCAD to monitor abandoned mine land subsidence, applied geotechnical monitoring and application of MULSIM/PC in a coal mine structural analysis; Mine ventilation, which includes papers on the application of graph theory to detect uncontrolled recirculation and selection of miner escape paths; Mine management, which includes papers on computer-based integrated mine management systems, manpower planning and a transportation and sales MIS system; Ground control II, which includes papers on predicting rock falls using discriminant analysis and geostatistics, the application of microcomputers in the systematic design of powered supports, and cost-based optimisation for roof control; Mine-plant planning and design, which includes papers on a CAD approach to mine planning and production scheduling, computer-aided evaluation of reserves and PERT analysis for the determination of optimum cycle paths in opencast mines; Information systems, which includes papers on the use of the OSM technical information processing system for three-dimensional analysis of overburden quality, storage and retrieval system of coal mine maps and design and application of the MIS system for geology and surveying; and Application of geostatistical methods in coal preparation and quality control II (3 papers).
