Coal Classification
Coal Classification is a way of sorting and categorizing different types of coal based on their quality and characteristics. It's like grading diamonds, but for coal. Mining professionals use this system to determine how valuable the coal is and what it can be used for, such as making steel or generating electricity. When someone lists this skill, they understand how to identify, test, and categorize coal samples, which is crucial for mining operations and sales. This knowledge helps companies know what they're mining and who might want to buy it.
