Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out through
ISO technical committees. Each member body interested in a subject for which a technical committee
has been established has the right to be represented on that committee. International organizations,
governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely
with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are described
in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the different types
of ISO document should be noted. This document was drafted in accordance with the editorial rules of the

Introduction
The ISO 22932 series has been prepared in order to standardize and to co-ordinate the global use of
technical terms and definitions in mining, for the benefit of the experts working on different types of mining
activities.
The need for the ISO 22932 series arose from the widely varying interpretation of terms used within the
industry and the prevalent use of more than one synonym.
