Abstract: An apparatus and method for filling boreholes with dry mass such sand, gravel, concrete and dry mortars or other similar materials from a deposit or a truck in blasting operations. The apparatus includes a container for storage of mass, conveying device with a conveyor screw for conveying the mass from the container into a hose and a compressed air supply for directing flow of the mass in the hose towards a dispenser. The compressor air supply is adapted to forcibly urge the mass into boreholes. The dispenser is adapted for positioning over the boreholes for filling with mass before blasting operations.
