Module Overview

This is an introductory module to tunnelling operations. In this module different tunneling methods are presented, including their application, history, limitations and strengths. These range from drill and blast to Tunnel Boring Machines (TBM), which have revolutionized the tunneling operations in recent years.

Learning Outcomes

  • List the geological conditions that affect tunneling operations
  • Explain the drilling and blasting processes as they relate to tunneling operations
  • Differentiate between machine tunneling in soft and hard ground and identify the type of equipment used in each case
  • Evaluate the application, history, limitations, and strengths of each tunneling method
