FIELD: blasting operations.
SUBSTANCE: invention is related to the field of mining and may be used for tamping of blastholes with tamping material at its installation around blasthole collar or installed close to blastholes. Device for tamping of blastholes includes actuator made of two parts, which are installed with the possibility of their closing and opening in horizontal plane with generation of V-shaped profile in working position, and system of shifting in the form of hydraulic cylinder connected to self-propelled vehicle. Actuator is arranged in the form of closing arrester-equipped mouldboards, which have profile direct or concave in horizontal or in vertical plane. System of shifting is made with the possibility of simultaneous or serial closing and opening of mouldboards and is equipped with hydraulic cylinders installed on every mouldboard.
EFFECT: higher efficiency of process of delivery and filling of blasting material into blastholes.
