ROLE OF THE TUNNELING MACHINE

TL;DRAbstract

TUNNELING MACHINE DESIGN PRESENTS MANY PROBLEMS WHICH ARE, FOR THE MOST PART, NOT RELATED TO ROCK FRACTURE, BUT RATHER WITH CRITERIA ASSOCIATED WITH OVERALL OPERATION. TUNNELAR DESIGN MUST BE SUCH THAT IT IS AN INTEGRATED PART OF THE GROUND SUPPORT, LINING, AND MATERIAL HANDLING SYSTEMS. THE PROBLEM OF NOISE AND SAFETY AS WELL AS TEMPORARY AND PERMANENT GROUND SUPPORT SYSTEMS ARE CONSIDERED. PROBE DRILLING, MUCK HANDLING AND TRANSPORT, AND OTHER BACKUP SYSTEMS ARE DISCUSSED. FACTORS THAT DETERMINE THE PERFORMANCE OF THE TOTAL TUNNELING SYSTEM ARE REVIEWED. FIGURES ILLUSTRATE HOW BECAUSE OF IMPROVED ROCK CUTTER DESIGN, THE SPECIFIC ENERGY REQUIRED TO FRACTURE THE ROCK HAS DECREASED OVER THE LAST DECADE, AND ALSO HOW THIS IS IMPROVING PENETRATION RATE. TUNNELER AVAILABILITY AND BACKUP SYSTEM CAPABILITY ARE DISCUSSED. THE 6 M LONG 18 FT 4 IN DIAMETER TUNNEL BORED UNDER LAKE HURON IS DESCRIBED TO ILLUSTRATE THE RESULTS OF AN OVERALL INTEGRATED TUNNEL BORING SYSTEM. THE REQUIREMENTS OF THE
