Préface

Cette nonne constitue la première édition de la nome CAN/CSA-M430. Elle a été élaborée dans le but de servir de guide pour la fabrication d’ouvrages de soutènement du sol et de protection des personnes qui travaillent dans l’industrie minière ou dam d’autres industries.

La norme ASTM Specification for Roof and Rock Bolts and Accessories (ASTM F432-88) et ses modifications subséquentes ont été soigneusement étudiées dans la préparation de la présente édition et nous désirons exprimer nos remerciements à cet organisme pour le matériel qu’il nous a fourni.

Cette norme a pour objet d’établir des règles d’utilisation minimales visant les organes et accessoires d’ancrage pour parois rocheuses. Lors de l’élaboration de cette norme, on a apporté une attention particulière à la prévention et à la sécurité des personnes, ainsi qu’à la protection contre les dommages matériels par l’observation de règles d’installation et d’entretien appropriées.

Domaine d’application

1.1

Cette norme énonce les exigences relatives aux caractéristiques chimiques, mécaniques et dimensionnelles des organes d’ancrage et accessoires pour parois rocheuses. Les organes d’ancrage visés sont les goujons à bouts filetés, les boulons à tête et les barres fendues en acier, les barres filetées et les boulons entièrement recouverts de résine, les dispositifs d’ancrage utilisés dans les points d’attache, les supports de toit en treillis, les boulons crénelés et autres dispositifs d’ancrage travaillant en friction. Ces organes d’ancrage constituent quelques-uns des types que l’on peut utiliser dans les ouvrages de soutènement du sol.

Preface

This is the first edition of CSA Standard CAN/CSA-M430. It was developed to serve as a guide for the protection against hazards to humans working in the mining industry, and/or any other industry using ground support systems.

In the preparation of this first edition the ASTM Standard Specification for Roof and Rock Bolts and Accessories (ASTM F432-88), and changes thereto, have been carefully studied and grateful acknowledgement is given to that organization for the material used.

The object of this Standard is to establish essential requirements and minimum standards for roof and rock bolts as well as accessories. In the preparation of this Standard consideration has been given to the prevention of hazard and injury to persons and property, and also given to proper maintenance and operation. Due regard has been given to recognized codes and standards now in force.

Scope

1.1

This Standard covers the chemical, mechanical, and dimensional requirements for roof and rock bolts and accessories. Addressed in this Standard are double-end threaded, headed, and slotted steel bars; fully grouted bolts and threaded bars; mechanical anchorage devices used for point anchorage applications; roof truss systems; partially grouted deformed bolts; and other frictional anchorage devices. All of these products represent various designs used for ground support systems.

1.2

The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are for information only.

Excluded are pressure generators, and internal valves of legs and rams (e.g. leg bottom valves, see EN 1804?2:2020).

NOTE

Some components are dealt with in other parts of this standard.

This document applies to hydraulic and electro hydraulic control devices at ambient temperatures from –10 °C to 60 °C.

This document identifies and takes into account:

possible hazards which can be caused by the operation of hydraulic and electro hydraulic control devices;
areas and operating conditions which can create such hazards;
hazardous situations which can cause injury or can be damaging to health;
hazards which can be caused by firedamp and/or combustible dusts.

This document describes methods for the reduction of these hazards.

A list of significant hazards covered appears in Clause 4.

This document does not specify any additional requirements for:

use in particularly corrosive environments;
hazards occurring during construction, transportation, decommissioning;
earthquakes.

A complete hydraulic powered roof support consists of the support units ( EN 1804-1:2020), legs and support rams ( EN 1804-2:2020) and the hydraulic and electro hydraulic controls ( EN 1804?3:2020). Each part of this multipart document addresses the safety requirements of the components mentioned in the scopes of the respective parts of this multipart series.

This document is not applicable to hydraulic and electro hydraulic control systems manufactured before the date of its publication.
