A research of rock pressure manifestations in the seam workings of seam 52 in “V. D. Yalevsky” mine is presented. It is shown that the inspected development workings advanced in a thick seam have a number of peculiarities determining the urgency of their stability research. It is noted that the researches are carried out in the workings subjected to coal extraction influence, as well as in the workings not subjected to that influence. A brief description of the research method including a visual examination of the mine workings and their support elements, instrumental studies of the border rock massif and the theoretical justification of the parameters of rock pressure are given. The following patterns: rock pressure manifestations mostly in the workings sidewalls, a positive time dynamics of rock pressure manifestations, and the increased intensity of manifestations in the workings roof after coal extracting in the face were recorded. The theoretical justification of rock pressure manifestations and the interpretation of the results of instrumental researches are given.
