Which mineral is commonly mined in West Virginia besides coal?

Limestone is commonly mined in West Virginia in addition to coal, primarily due to its wide range of industrial uses. It plays a crucial role in the production of cement, lime, and glass, and is also used in agriculture to improve soil quality. The abundance of limestone deposits in the region makes it a significant mineral resource and an important contributor to the state's economy.

In contrast, while gold and silver mining has taken place in various regions, it is not a primary mining activity in West Virginia today. The presence of gemstones, although they can be found, does not constitute a major mining industry within the state. Therefore, limestone stands out as the most prevalent mineral mined alongside coal in West Virginia.
