ABSTRACT
M i n i n g and geological conditions in all the working mines of Western Donbass are the fol-
lowing: the sequence of preparation is level by level, mining system is the longwall method (from
700 to 1600 m) by coupled or single faces with individual lengths of 150-200 m, mining of seams
is carried out in descending order and it takes 2-2,5 years to mine two mining blocks on neigh-
bouring seams with longwalls working in stepped configuration. The mining blocks are developed
by raises, all faces are equipped with mechanized longwall sets.
