Abstract

All the mathematical models for mine climate prediction are based on the numerical values of thermal properties of associated rock formations. Among them thermal conductivity is an important parameter and requires speical attention. In the present paper a simple method of in-situ measurement of thermal conductivity in coal mines is discussed. During experimentation 20 measurements were taken at number of locations in different collieries in different seams. Altogether 9 holes were drilled and used for underground experimentation. From these measurements average calculated values of in-situ effective thermal conductivity are presented.
