Thermal Monitoring of Geological Changes during Excavation

Abstract

The objective of this program is to determine the feasibility of using measurements of local temperature distributions along the walls of an excavation as an aid in predicting hazards to tunneling operations. The goal of the first two quarters was to gather information pertaining to possible temperature conditions, rock formations and general mining environmental conditions as well as information about the state of the art in non-contact temperature measuring devices. Calculations were performed on theoretical models of temperature fields around geologically different areas in an otherwise homogeneous rock matrix, and numerical data were obtained which are pertinent for the design of the radiometer.
