What does the term "overburden" refer to in mining?

The term "overburden" specifically refers to the layer of soil and rock that lies above a mineral deposit. In mining, overburden must be removed to access the underlying minerals, making it a crucial concept in both surface and underground mining operations. Understanding overburden is vital for several reasons: it affects the design of the mining operation, the methods used for extraction, and the management of waste materials. It is important for mining engineers to evaluate the volume and characteristics of the overburden, as it influences the costs related to removal and the overall environmental impact of the mining project.

In mining practice, effective management of overburden can help minimize disruption to the surrounding environment and contribute to more sustainable mining practices. Recognizing overburden is essential for planning and executing mining activities efficiently and responsibly.
