RAPID EXCAVATION: SIGNIFICANCE-NEEDS-OPPORTUNITIES

THE GROWING NATIONAL CONCERN FOR ENHANCING AND MAINTAINING THE QUALITY OF THE ENVIRONMENT IN THE FACE OF GROWING RESOURCE-AND-URBAN-DEVELOPMENT DEMANDS WOULD BE SUBSTANTIALLY LESSENED IF GREATLY IMPROVED UNDERGROUND- EXCAVATION TECHNOLOGY WERE AVAILABLE. THIS REPORT DISCUSSES AT LENGTH SOME OF THE AREAS WHERE RESEARCH IS NEEDED. AMONG THOSE MENTIONED ARE THE IMPROVEMENT OF PROCESSES AND EQUIPMENT FOR BORING, MUCK REMOVAL, AND SUPPLY HANDLING METHODS. SUPPORT FOR TUNNELS, BOTH PERMANENT AND TEMPORARY, FOR LONG TUNNELS OR SHORT TUNNELS, MUST BE IMPROVED SO THAT THEY CAN BE PLACED WITH THE SPEED NECESSARY TO KEEP UP TO ADVANCED MINING MACHINES. IMPROVED TECHNIQUES FOR MEASURING SUBSURFACE STRESSES, FOR DETERMINING ROCK AND GROUND WATER CONDITIONS AND FOR MEASURING ELECTRICAL, THERMAL OR MECHANICAL BEHAVIOR OF ROCKS MUST BE DEVELOPED. OVER AND ABOVE CURRENT GOVERNMENT AND INDUSTRY RESEARCH AND FUNDED RESEARCH PROGRAM SHOULD BE UNDERTAKEN IMMEDIATELY. DEVELOPMENT EFFORTS, A 10-YEAR, $200 MILLION, FEDERALLY FUNDED RESEARCH PROGRAM SHOULD BE UNDERTAKEN IMMEDIATELY.
