The author attempts to predict how drilling and tunnelling techniques are likely to develop between now and the year 2000. Reference is made to the development, over 100 years, of rock drills while drilling and blasting have remained the chief method of tunnelling in hard rock. A review is made of various methods proposed for disintegrating rock, which are compared with existing mechanical methods. Prediction for tunnelling processes suggest more highly automated machines than now, controlled by less-qualified operators. A comparison is made of the use and development of pneumatic and hydraulic drills, and the advantages and disadvantages of the fullface tunnel boring method are discussed. Finally, the author describes existing rock removal methods, and the increasing importance of remote control for loading work in the future. (TRRL)
