Essay

The dissertation is dedicated to technology parameters of high productive face complexes crossing of technogenic zones that form around mine working during the longwall advance. It is established that stress-strain state of technogenic zone rock massif has directly proportional dependence on distance from the longwall face, parameters of abutment pressure and their time deposition, and also on the structure of the massif. The dependences are gained as to technogenic processes influence on vector direction change of bending moment action during technogenic zones crossing in roof rocks from positive value to negative due to combination of the mine working width and longwall working space that advances. As a result of introduction of technological recommendations for stoping of technogenic zone of seam at 2-nd north longwall of "Krasnolimans'ka" mine, the economic effect made up 1.6-2.3 mln. UAH.
