Technical Specifications for the Application of Steel Slag in Mine Remediation and Backfilling

1 Scope

GB/T 47193-2026 is the Chinese national standard covering filling worked-out mine voids with steel slag - a use for a material produced in enormous quantity, provided its expansion has stopped and its leachate will not reach the groundwater. First edition, in force since 1 September 2026, and it depends on the stability test GB/T 24175-2026 revised in the same period. It was issued on 27 February 2026 and has been in force since 1 September 2026, as a first edition. The document is under the responsibility of the China Iron and Steel Association. This page is published from the official record of the 2026 edition; the clause text of a standard this recent is not yet in circulation, and the figures, limits and tables it contains are those of the document itself, delivered in full with the English translation.

This document specifies the basic requirements, work procedures, open-pit mine site selection requirements, mine baseline survey, and steel slag for mine restoration and backfilling. Slag sampling and performance requirements, environmental risk assessment, pollution prevention and control requirements, backfilling operation requirements, environmental quality monitoring and record keeping and post-construction management Require. This document applies to the backfilling of open-pit mines using steel slag.
