CLASSIFICATION OF COAL SEAMS BY FEATURES OF GEOLOGICAL STRUCTURE AND CHARACTERISTICS OF BREAKING



Based on the earlier research findings on characteristics of breaking and geological structure, the database has been compiled for coal seams under mining in the territory of Russia. The sco of the research embraced around 300 coal seams for which the structural behavior and contents of pe coal, dirt bands and solid inclusions were determined. To this effect, the data of in-situ instrumental measurements of strength and structural features were used. Additionally, statistics and geological description of coal seams by structural columns were involved. The research was aimed to use the resultant database for typification of coal seams by their geological structure and breaking characteristics. The developed typifications served for classification of coal seams as media subjected to disintegration. The proposed procedure is a tool for selecting parameters of coal cutting machines, and the classification allows ranking of coal seams by the integral structure–breakability estimate on the scale from the easiest to the most difficult.
