FIELD: prospecting of technogenic mineral deposits. SUBSTANCE: the offered method includes noncore hole drilling by intervals with drillings brought to the surface using wet pneumatic flushing of hole bottom. Drillings brought to the surface are conveyed by air flow from the hole mouth to pile them in form of truncated cone. Before taking sample of drillings from each interval of hole, drilling is stopped. After taking samples, drillings from hole mouth are removed. EFFECT: higher efficiency of the method due to increased confidence and representation of taken samples. 2 dwg
