HARD ROCK TUNNELLING MACHINES

A BRIEF HISTORY OF TUNNELLING MACHINES PRECEDES AN OUTLINE OF CONVENTIONAL AND SOFT GROUND (SHIELD) TUNNELLING METHODS. HARD ROCK TUNNELLING MACHINES MADE IN THE LAST 15 YEARS ARE EXAMINED IN DETAIL, THEIR PERFORMANCES BEING COMPARED WITH THOSE OBTAINED BY CONVENTIONAL METHODS. THE ADVANTAGES AND DISADVANTAGES OF MACHINE TUNNELLING ARE DISCUSSED, AS ARE THE MAJOR PROBLEMS ASSOCIATED WITH THEIR USE. COSTS OF CONVENTIONAL AND MACHINE TUNNELLING ARE EXPLORED: AND THE APPLICABILITY OF HARD ROCK TUNNELLING MACHINES TO ALL TYPES OF UNDERGROUND MINING IS DEMONSTRATED. /AUTHOR/
