Precision and Low Impact Mining

The Challenge

The Western Australian mining industry has seen an increasing focus on precision and low impact mining approaches, driven by both industry and government initiatives, such as the adoption of autonomous haulage systems, and the implementation of advanced environmental monitoring technologies. Despite these advancements, there are still challenges to overcome, including the rehabilitation of legacy mine sites, the management of water resources, and the engagement of Traditional Owner communities in decision-making and project milestone processes.

Context:

The minerals sector is undergoing a significant global shift towards responsible practices as a result of growing community environmental and social concerns, changing regulations, and increasing pressure from stakeholders. Initiatives such as the International Council on Mining and Metals (ICMM) and the United Nations Sustainable Development Goals (SDGs) provide platforms for dialogue and cooperation on sustainable mining issues. Emerging trends in precision and low impact mining include collaboration and knowledge exchange among mining nations to share best practices, and development of innovative technologies to address common challenges.

While Western Australia is a major contributor to Australia’s mining industry, and plays a crucial role in its economy, generating employment, export revenue, and economic growth, there remains opportunities for the state to position itself as a global leader in responsible mining regulation, practices and innovation.

MRIWA encourages and supports precision and low impact mining research which advances technologies, provides clean energy solutions and responsible practices to optimise resource extraction and management, minimise environmental disruption and uphold social values.
