Popis:	The main group of mining systems for thick steeply dipping coal seams with stowage of the worked-out area, adopted recently in industrial trials in pits in the Kuznetsk coalfield, involves advance of the extraction front to the rise of the seam by means of successive mechanized extraction of narrow strips to the strike. This group of new systems has many features that are almost identical with those used for some time in pits in this coalfield in systems of mining with laterally inclined and sloping panels with hydraulic stowing. Thus the data, resulting from an investigation of the development of roof displacements during extraction of a single laterally inclined panel or of all the panels worked up to the time of scheduled advance of the extraction front, can be used to predict rock pressure phenomena in similar new technological schemes.
