FIELD: mining.
SUBSTANCE: invention relates to mining industry and can be used for mechanized excavations and cleaning excavation in mines and ore mines in small abrasive rock massifs. Executive body of the aggregate for tunneling works includes a body, a cutting element and a hydrotrap. Cutting element is made in the form of a flat cutting bar mounted on a movable carriage which is provided with a feeder and spacer cylinders for cutting slots in a mountain massif. Inside the body of the executive body cylindrical hydrotrapers are installed in an amount not less than five, made with the possibility of two-sided action on the lateral surfaces of the slots in the mountain massif.
EFFECT: increased device capacity with a decrease in specific energy consumption of the destruction process of a massif and a decrease in the amount of pulverized fractions in breaking products, as well as increased functionality of the device.
