All the mathematical models for mine climate predication are based on the numerical values of thermal properties of associated rock formations. Among them thermal conductivity is an important parameter. In the present paper the probe method used for thermal conductivity determination in laboratory is discussed. Using this method, thermal conductivity of 9 coal samples collected from different underground coal mines, 7 samples of schist and 69 samples of variety of sandstones collected from different boreholes is determined. Also, porosity and surface area of coal samples is determined using automatic apparatus PASCAL 240. From these measurements effect of porosity and surface area on thermal conductivity is also discussed.
