Abstract

See full text

A method and apparatus for controlled charging of blasting boreholes with a flowable/pourable explosive, in particular in open-cast mining, includes: providing a radar head with at least one radar unit operated in a non-rock penetrating frequency range; arranging the radar head on a pulling element; introducing the radar head into the borehole in that the radar head is lowered into the blasting borehole in an arrangement at the pulling means from an upper aperture opening of the blasting borehole; and detecting at least one measurement value comprising a base distance of the radar head from the blasting borehole base and/or a charge level distance to determine the charge level of the explosive in the blasting borehole; and/or comprising the shape of the jacket section over at least a portion of the depth of the blasting borehole by means of the operation of at least one of the radar units.
