GOAF Meaning and
Definition
-
Goaf is a term used in mining and refers to a specific area or space that has been left underground after the extraction of minerals or coal. It refers to a void or cavity that remains after the mining process is complete. This term is primarily used in the context of underground mining activities.
The goaf is a result of the removal of valuable minerals or coal from the strata beneath the earth's surface. In the mining process, miners create excavations and remove the desired material, leaving behind the goaf. The size and shape of the goaf can vary depending on the mining technique employed and the geological conditions of the area being mined.
The goaf can pose several challenges and potential risks in the mining industry. It can lead to subsidence, causing the ground above it to sink or collapse. This can result in structural damage to infrastructure and may pose risks to the safety of workers or nearby communities.
To mitigate these risks, various measures may be taken in mining operations, such as backfilling the goaf with inert materials to help stabilize the ground. Additionally, proper monitoring and control of the ground movement are essential to prevent accidents or geological disasters.
In summary, goaf refers to the cavity or space left underground after minerals or coal have been extracted through mining. It is a potential hazard that requires proper management and mitigation in order to ensure the safety and stability of the mining operations and surrounding areas.
