FIELD: mining, particularly earth-moving machine used for open-cast mining of minerals included in solid enclosing rock and for slice mining.
SUBSTANCE: device comprises basic machine, basic machine frame hingely connected with rotary executive tool frame and rear support frame for executive tool. The executive tool has conveyer. Device includes additional hydraulic pump having independent power drive and active mechanical ripper. Active ripper teeth are spaced one from another along the full rotary executive tool cutting width and are provided with high-frequency hammers with hydraulic striker activation system. The strikers are activated by additional hydraulic pump. The teeth may be displaced in vertical plane.
EFFECT: extended field of continuous mining technology application and increased intensity of mining works lowering.
