DRILLING OF TUNNELS WITH THE USE OF EXPLOSIVES

THE DRILLING OF UNDERGROUND TUNNELS INVOLVES A NUMBER OF PROBLEMS, DEPENDING ON THE TYPE OF ROCK AND THE LOCATION OF THE WORK. THE IMPOSSIBILITY OF UTILIZING FREQUENT VERTICAL SHAFTS UNDER URBAN ZONES REQUIRES AN EVER MORE WIDESPREAD USE OF SO CALLED CONTINUOUS EXCAVATORS, WHICH HAVE ALREADY BEEN EXTENSIVELY USED IN MINING PROJECTS. THESE TYPES OF MACHINERY CAN BE MODIFIED & IMPROVED IN ACCORD WITH THE TYPE OF TUNNELLING TO BE PERFORMED. SPECIALIZED ADAPTATIONS USED IN EUROPE AND AMERICA ARE DESCRIBED, AND INFORMATION IS COLLECTED THAT IS USEFUL WHEN SELECTING THE BEST TYPE OF EQUIPMENT FOR A PARTICULAR PROJECT. /AUTHOR/
