This document establishes a classification of mining methods based on specification such as ore grade and recovery, cost of infrastructure, ore extraction, labour and machine costs, underground support costs and geotechnical factors.
Abstract
Overview
ISO 21557:2025 - Mining - Mining methods - Classification and specification (First edition, 2025) defines a uniform framework for classifying mining methods. The standard helps practitioners select and specify surface and underground mining methods by linking method choice to measurable specifications such as ore grade and recovery, infrastructure and extraction costs, labour and machine costs, underground support costs, and geotechnical factors. promotes comparability and consistency of mining information across feasibility studies, design phases and regulatory submissions.
