FIELD: mining. ^ SUBSTANCE: invention relates to mining industry and may be used to win bedded minerals along bed hypsometry, also under complicated mining and geological conditions. Winning machine for bedded minerals includes sections of bearing powered movable support with longitudinal guides, where sections of guard shield are installed, being connected to sections of actuator with drive installed along front of bed winning. Winning machine is additionally equipped with brackets having cutters for damage of face from surface along cutting lines directed along front of bed winning with pitch providing for reservation of pillars between them. Brackets with cutters are joined to each other by sections of actuator with drive. Brackets with cutters are rigidly installed on sections of guard shield with drive of its motion along longitudinal guides of sections of bearing powered movable support. ^ EFFECT: reduced power intensity of face damage, provision of monitoring of machine position relative to bed, increased efficiency of machine, reduced dilution. ^ 3 cl, 5 dwg |
