Coal Grade
Coal Grade refers to the quality and characteristics of coal, which is important in mining operations. It's similar to how diamonds are rated for quality, but for coal. When someone mentions coal grade in their resume, they're talking about their experience in determining, managing, or working with different qualities of coal. The grade affects how the coal can be used - some grades are better for making steel (metallurgical coal), while others are better for producing electricity (thermal coal). Understanding coal grades is a key skill in coal mining because it directly impacts the coal's market value and its suitable applications.
