ABSTRACT
The 590 belt entries and the 592 upper entries of the C6 seam mine field have been selected as an object of mining research performing and being the variants for various basic schemes for the roof-bolts setting in the roof. The research was carried out in the area of the eastern wing of the inclined part of the C6 seam mine field, where three panels of 590, 592 and 594 longwall faces were mined. Mining and geological conditions are approximately the same both in depth of development and in structure, as well as the properties of the coalbearing strata. One of the phenomena that have a negative effect on the stability of the frame support and the mine working in general, is the asymmetric deformation of the frame, caused by an increased load from the side of the 590 longwall face.
