Methodology of multi-dimensional classification according to the reference points for the determination of the degree of coal spontaneous combustion at the Tainin section of Kansk Deposit of Kanskoy Basin

Abstract

The paper presents the results of studies of coal spontaneous combustion and forecast of Tainin section of Kansk Deposit of Kansko-Achinsky basin. To this end, a new original methodology has been applied, based on the rank data model and the idea of classifying these data by «proximity» to reference groups of observations. As a result of studying of a geological structure of the investigated layer, physical and chemical researches and the analysis of statistical data on self-ignition of coals, the geological factors of self-ignition of coals and boundary values of their parameters of different degree of danger of self-ignition have been established. Transition from the initial data of a coal bed to a rank scale has been carried out with the use of standards (boundary values) of levels of danger of spontaneous combustion of coals. The obtained data were used in the construction of the self-ignition prediction map of coal bed «Powerful» (Moschnyi) using the program ArcMap 10.2 from the family of geographic information programs ArcGIS.
