UNDERGROUND MINING, MINE SYSTEMS DESIGN: THE NEXT EFFORT WILL FOCUS ON TUNNELING

THE VALUE OF SUBSURFACE EXCAVATION FOR CIVIL AND MILITARY USE, AND NOW FOR CONSERVING THE LAND AND ITS RESOURCES ARE REVIEWED. THE PRESENT TECHNOLOGY OF UNDERGROUND EXCAVATION IS INADEQUATE. SUBSTANTIAL IMPROVEMENT IN SUBSURFACE EXCAVATION TECHNOLOGY IS MANDATORY AND THE EQUIPMENT AND TECHNOLOGY ADVANCES ARE REVIEWED. IT IS POINTED OUT THAT ANY EXCAVATION SYSTEMS MUST COMPRISE FOUR PRINCIPAL TECHNOLOGIC PARTS OF SUBSYSTEMS: (1) ROCK DISINTEGRATION, (2) MATERIALS HANDLING, (3) GROUND CONTROL, AND (4) ENVIRONMENTAL CONTROL. THE ADVENT OF THE MECHANICAL TUNNEL-BORING MACHINE HAS OPENED NEW VISTAS FOR IMPROVING TUNNELING TECHNOLOGY BY ELIMINATING THE CYCLE INHERENT IN CONVENTIONAL DRILL-BLAST TUNNELING SYSTEMS. MECHANICAL BORING MACHINES ARE DISCUSSED. THE PROBLEM OF TRANSPORTING MATERIAL UNDERGROUND IS DISCUSSED AS WELL AS THE PROBLEM OF WATER INFLOW, GAS OUTBURSTS, VENTILATION, AND TEMPERATURE CONTROL. VALUABLE TOOLS FOR CHARACTERIZING SURFACE CONDITIONS WILL BE THE USE OF STATISTICAL CORRELATION TECHNIQUES AND COMPUTERS FOR MODELING GEOLOGIC SITUATIONS. THE CHALLENGE IS THE DEVELOPMENT OF RAPID UNDERGROUND EXCAVATION TECHNOLOGY THAT WILL PERMIT FULL, EFFICIENT UTILIZATION OF THE LAND DEPTHS. CURRENT MINE RESEARCH IN GROUND CONTROL, ROCK DISINTEGRATION, MATERIALS HANDLING, AND ENVIRONMENTAL CONTROL AND MINES SYSTEM DEVELOPMENT ARE SUMMARIZED.
