Problem of constructing fundamental workings at great depths
Rock deformations around underground workings in several mines of Donets basin are due to wrong type of props used in heaving rocks, sudden change of underground working's profile, and effect of support pressure created during mining operations in closely spaced coal beds; characteristics of performance of 5 types of props used in mines; rock mechanical characteristics and recommendations concerning mining operations at deep levels.
