A blended explosive generally refers to a mixture of ammonium nitrate and emulsion. A range of blends are available from straight ANFO through a 50/50mix to straight Emulsion.

Blends containing more ANFO than Emulsion are known as Heavy ANFO's or HANFO

Blends containing more Emulsion than ANFO are known as Doped Emulsion

Blends containing more than 40% Emulsion have good water resistance and where Emulsion content is over 50% the product is considered suitable for loading into fully wet holes.

Blends containing more than 50% Emulsion generally need to be chemically gassed for sensitivity.
