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.

An apparatus for filling boreholes with mass before blasting operations, the apparatus comprising:
- a container for storing mass;
- a conveyor screw at bottom of the container for feeding mass into a hose;
- a whisk or vibrator mounted above the conveyor screw in the container for guiding the mass into the conveyor screw for feeding into the hose;
- a compressor having pipes for supplying highly compressed air into the hose;
- a vacuum pump for creating suction pressure at the end of the hose;
- and
- a dispenser for poring the mass into the boreholes, wherein a pipe from the compressor is connected into the hose immediate at the conveyor screw for directing flow of the mass towards the dispenser, and a pipe into the vacuum pump to immediately provide extra lifts for discharging the mass into borehole from the dispenser.
