Sostoyanie krepi i kharakter proyavlenii gornogo davleniya v kapital'nykh i podgotovitel'nykh vyrabotkakh glubokikh shakht donbassa
Condition of roof supports and nature of rock pressure in permanent and development workings of deep mines in Donets basin; conditions of roof supports studied in 28 deep mines of Donets basin indicate that rock pressure becomes three-dimensional below 700 to 800 m level; this requires use of yielding roof supports and arches.
