The Study of the Rational Direction the Mining Development in the Development of Marble Limestones

The system of cracks in hard rock deposits has been investigated. Considering the values depending on the angle of displacement of the rock, the line of free displacement of the rock is determined. The study takes into account the distances and direction of movement of cracks lying along the horizons, based on a total station survey. During the grouping process, the cracks are divided into the first and second sequences. The first one had cracks formed as a result of subsidence of the massif, and the second one took into account cracks formed in the ground. The main point of the article is the development of granite rocks without violating their quality during the development process. This issue is currently relevant for the development of rocks divided into blocks.
