THE UTILIZATION OF THE LOGGING CURVES FOR DISCRIMINANT ANALYSIS OF COAL AND CARBONACEOUS MUDSTONE

Fan Jun Li Jianlin Pan Jianxi (The Geochemical and Geophysical Exploration Team of the Shaanxi Bureau of Geology and Mineral Resources)  
In order to divide accurately the coal and carbonaceous mudstone of the Carboniferous—Permian coal field in Fugu of the northern Shaanxi,and by means of the method of probability statistics,the writers made out the statistic laws of physical properties and extracted the diseriminant form- ula:P=0.015ρ_s-0.77γ′.Using the P value determined by the apparent resis- tivity and the gamma value,they discriminated and analyzed coal and car- bonaceous mudstone.Proved by practical utilization,this method has an evident effect and very lower errors.Finally,the extension and the dem- ands for utilizing logging curves have been discussed in this paper.
