Structures for mine shafts — Part 3: Sinking stages
This document specifies the design loads and the design procedures for the structural design of stages and components of stages. The loads specified in this document are not applicable for the design of stage ropes or sheaves. Rope sizes are determined in accordance with other standards. This document does not cover matters of operational safety, or layout of the sinking stage. This document adopts a limit states design philosophy.

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 documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www .iso .org/directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of
any patent rights identified during the development of the document will be in the Introduction and/or

Introduction
Many mining companies, and many of the engineering companies which provide designs for mines,
operate globally so ISO 19426 was developed in response to a desire for a unified global approach to
the safe and robust design of structures for mine shafts. The characteristics of ore bodies, such as
their depth and shape, vary in different areas so different design approaches have been developed and
proven with use over time in different countries. Bringing these approaches together in ISO 19426 will
facilitate improved safety and operational reliability.
The majority of the material in ISO 19426 deals with the loads to be applied in the design of structures
for mine shafts. Some principles for structural design are given, but for the most part it is assumed
that local standards will be used for the structural design. It is also recognized that typical equipment
varies from country to country, so the clauses in ISO 19426 do not specify application of the principles
to specific equipment. However, in some cases examples demonstrating the application of the principles
to specific equipment are provided in informative Annexes.
