ABSTRACT

This paper presents the results of mathematical modeling of rock mass stress-relieving
process performed using Itasca’s FLAC finite-difference software. The main goal was
determination of the optimal geometry and location of slots or fractures to increase the
stress-relief area of the coal measure rock. The resulting stress pattern was analyzed and
recommendation for degasification works of coal seams was made.
