Ash Content
Ash Content is a crucial measurement in the coal mining industry that tells how much non-burnable material is present in coal. Think of it like checking the purity of gold - the lower the ash content, the better quality the coal is. When someone lists ash content experience on their resume, it means they've worked with testing or managing coal quality. This is important because coal with high ash content is less valuable and can cause problems in power plants and other industrial uses. Mining companies rely on this measurement to price their coal and ensure it meets customer requirements.
