Notes:
A novel ring heat source probe based on three-dimensional transient heat conduction from a point heat source is applied to measure in situ wall-rock thermal conductivity in mine pits. The calibration is based on two reference materials. The data are processed digitally, using an acoustically controlled channel selector. The application of a fully automatic control technique by a microcomputer program results in successful establishment of a quick and portable one-button triggering, in situ wall-rock thermal conductivity meter for mine pits.
