What is highwall mining?

Highwall mining is a hybrid form of mining that extracts coal from the base of an exposed highwall. It is used when surface mining reaches its economic limit and allows access to remaining reserves without the need for underground mining.

How does highwall mining equipment work?

Highwall mining equipment includes highwall miners, augers, and mining tools that extend into the wall to retrieve coal. The equipment operates remotely, reducing the risk for workers and enhancing safety.

What are the advantages of highwall mining?

Highwall mining offers a cost-effective method of extracting coal compared to underground mining, with less environmental impact. It allows access to additional resources with minimal surface disruption.

How does highwall mining improve resource recovery?

Highwall mining increases resource recovery by accessing coal seams that are not economically viable for surface or underground mining. It maximises coal extraction, reducing the amount of unmined resources.

What safety precautions are required for highwall mining?

Safety precautions for highwall mining include slope stability monitoring, real-time equipment diagnostics, and ensuring proper ventilation to minimise dust exposure and gas buildup, protecting both the environment and workers.
