This paper presents examples of SkyTEM helicopter-borne time-domain (HTEM) systems recently applied to solve a variety of environmental and engineering problems. The mining industry has traditionally used airborne geophysical methods almost exclusively for mineral exploration. However, this paper provides examples of how HTEM data can inform decisions relevant for mine operations. Examples comprise delineation of aquifers that may (1) pose a risk to underground workings and (2) may be threatened by seepage from tailing dames, delineation of clay caps that can act as shallow gas traps endangering drilling operations, and mapping of faults and taliks the location of which must be considered when placing mine infrastructure.
