Session Start Date

5-6-1984

Abstract

Several case histories are presented in order to highlight the way in which unexpected adverse geological conditions promote large delays in rock tunnelling. These are selected from tunnels which have been excavated by drill and blast, roadheader and fullface tunnel boring machines. In each case the important properties of rock affecting the progress rates obtained are identified together with the nature of the tunnelling problems encountered.

Mechanised Rock Tunneling in Adverse Conditions

Several case histories are presented in order to highlight the way in which unexpected adverse geological conditions promote large delays in rock tunnelling. These are selected from tunnels which have been excavated by drill and blast, roadheader and fullface tunnel boring machines. In each case the important properties of rock affecting the progress rates obtained are identified together with the nature of the tunnelling problems encountered.
