Annotation:

The result of rock massif state analysis during coal-face working in the increased strata pressure areas are described in the article. The behavior of the rock massif during crossing of area with increased pressure by the coalface working from the side of rock mass and during transition of longwall face from the unloaded area in the area of with increased strata pressure is considered. The reasons of technogenic violations appearance are set for the concrete longwall on the basis of instrumental supervision data.
