Determination of Cuttability of Coal Seams and the Surrounding Rocks in Underground Conditions by Means of a Device Designed at GIG

摘要

A device for cuttability measurements of coal seams and the surrounding rocks in underground conditions, designed at GIG has been presented in the paper. Part of the article is dedicated for a review of cuttability of rocks measurement methods, hitherto applied in Poland and abroad. After that, the main elements of the device have been described as well as a procedure for performing measurements in underground conditions. Simultaneously, the examples of the underground measurement results have been given.
