FIELD: mining.
SUBSTANCE: invention relates to the field of mining to the development of coal deposits. Method of preparing the excavation pillars when working out anthracite strata with cleavage cracks in the plow complex, including the installation of the working body of the plow complex parallel to the direction of the cleavage cracks, that when working out an anthracite of increased strength before the start of the operation of the plow complex, water is injected into the formation of increased pressure through the wells, drilled across the cleavage cracks, located at a distance from each other, allowing to form a single zone of moistening.
EFFECT: invention makes it possible to increase the load on the lava, improve the technical and economic indicators and ensure safe working conditions.
