ABSTRACT OF THE DISCLOSURE An apparatus for the charging of rising drill-holes, preferably large holes of diameter approximately 100 mm or more, with pipecharges. Apparatus of the present invention makes it possible to feed charges into the hole in such a way as to fill the hole effectively while making it easy to apply the necessary firing gear (primer and detonator). The charging apparatus comprises a stand capable of being aligned with the mouth of a drillhole by pivoting on a fixed surface. The stand includes a lifting means which is provided with a rest platform capable of travelling towards and away from the drillhole, to carry pipecharges. That part of the stand which is aligned with the drillhole comprises a guide unit which is arranged to guide the pipecharges into the drillhole as the rest platform travels towards the said drillhole. The pipecharges are re- tained in place after the lift by retaining means.
