ANTICIPATING THE UNEXPECTED - FLOOD, FIRE OVERBREAK, INRUSH, COLLAPSE

The authors have personal experience of many tunnelling incidents. None involved injury, but costs have been very high, sometimes as much as the Contract value. Similar incidents will continue to occur because the cost of trying to avoid all risks is high. Post mortem studies can highlight failures in the procedures being followed before the disaster, and are therefore valuable aids to safeguarding the remainder of the work. (A) Case studies of 14 incidents are presented. For the covering abstract see IRRD 896729.
