ISO/TC 82/WG 4 - Structures for mine shafts

This document specifies the design loads and the design procedures for the design of structures used in underground mines. It covers all steel and concrete structures used in underground mines, irrespective of the depth of the mine or the product being mined. This document adopts a limit states design philosophy. Typical underground structures covered by this document include, but are not limited to: — box front structures at the bottom of rock passes; — conveyor gantry and transfer structures; — chairlift support structures; — crusher support structures; — fan support structures; — fixed or retractable arresting structures for ramps (see ISO 19426-5); — foundations for pumps, fans, winches and underground winders; — high-pressure bulkheads; — monorails; — overhead crane gantries for workshops, pump stations and sub shaft winder chambers; — settler structures; — silo bulkhead structures; — silo structures; — structures supporting loose rock; — tip structures, including dump structures; — underground head frames; — ventilation control doors and other ventilation structures; — walls and floors for safety bays, refuge stations and sub-stations; — water control doors; — water retaining structures. This document does not cover matters of operational safety or layout of the underground structures.

This document specifies the design loads and the design procedures for the design of rope guides and rubbing ropes used for guiding conveyances and preventing collisions in vertical mine shafts for permanent operations. It covers personnel and material hoisting, as well as rock hoisting installations. There are no fundamental limitations placed on the size of conveyances, the hoisting speeds, shaft layout configurations, or the shaft depth. This document can be applicable to shaft sinking operations when kibbles run on the stage ropes. There are many reasons, based on technical, timing, and cost factors, why rope guides are selected or not for a particular application, following careful assessment at feasibility stage of any project where rope guides are considered. This document provides some comments regarding the advantages and disadvantages of using rope guides compared to rigid guides, and specific design aspects for consideration when using rope guides. However, it is primarily intended to provide the technical information required to ensure good engineering of shafts where rope guided hoisting is the chosen solution. This document does not cover matters of operational safety.

This document specifies the design loads and the design procedures for the structural design of headframe structures of mine shafts and their components for permanent and sinking operations. The headframe includes all structures and their foundations, that are required at the head of all vertical and decline mine shafts for the purposes of supporting and installing winding and sinking ropes, conveyance guides, rope guides and rubbing ropes, equipment for loading and unloading conveyances, safety devices, as well as ancillary sinking and maintenance equipment. The headframe also includes the bank and sub-bank levels. This document does not cover matters of operational safety or layout of the headframe. This document adopts a limit states design philosophy.

This document specifies the terms and definitions related to the structures for mine shafts, used throughout ISO 19426. Terms used in mining can vary from conventional engineering usage, and they vary quite considerably between different countries. For this reason, alternative terms are provided in many of the entries. The preferred terms, given in bold type, are those used throughout ISO 19426. It is assumed that users of this document are familiar with mining, so common terms with normal dictionary usage are not defined. Also, no definitions are provided for terms that can be widely used in mining but are not explicitly used in ISO 19426.

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.

This document specifies the loads, the load combinations and the design procedures for the design of shaft system structures in both vertical and decline shafts. The shaft system structures covered by this document include buntons, guides and rails, station structures, rock loading structures, brattice walls, conveyance and vehicle arresting structures and dropsets, services supports, rope guide anchor supports and box fronts. Rock support is excluded from the scope of this document. This document does not cover matters of operational safety, or layout of the shaft system structures This document adopts a limit states design philosophy.

This document specifies the loads, the load combinations and the design procedures for the design of the steel and aluminium alloy structural members of conveyances used for the transport of personnel, materials, equipment and rock in vertical and decline shafts. The conveyances covered by this document include personnel or material cages (or both), skips, kibbles, equipping skeleton cages, inspection cages, bridles, crossheads and counterweights. This document is not intended to be used for the design of ropes, sheaves or attachments. Rope sizes are determined in accordance with other standards. This document does not cover chairlifts. This document does not cover matters of operational safety or layout of conveyances. This document adopts a limit states design philosophy.
