Abstract: The present invention relates to improved emulsion explosive compositions and their manufacture. More particularly, the invention relates to the provision of improved emulsion explosive compositions having reduced tackiness which permits them to be handled without difficulty and increased rigidity which enables them to maintain desired column height. The improved compositions also evince enhanced detonation sensitivity, improved shelf life over long periods of storage and greater resistance to shock or shear desensitisation though the precise reasons for these improvements are not always clear.
