Coal is also used in the steel manufacturing process, which utilizes coke, a byproduct of burning coal. Some structures and industrial installations still use coal for heating the actual structure, though these are becoming quite rare. Most modern industrial uses for coal, outside of electricity production, involve large coalfired furnaces.
Different types of coal have different uses. Steam coal also known as thermal coal is mainly used in power generation. Coking coal also known as metallurgical coal is mainly used in steel production. Other important users of coal include alumina refineries, paper manufacturers, and the chemical and pharmaceutical industries.

In the 1960s, smaller coal companies merged into larger, more diversified firms. In 2008, competition in the coal mining industry became more intense than ever, leading to a demand for better technology and new mines. History of Mining Technology. In the beginning, miners used primitive tools for digging.
The main use of coal is in industry. Coal is used to generate electricity, it''s used for smelting metals, and other manufacturing processes that require a high temperature.
Due to growth in surface mining and improved mining technology, the amount of coal produced by one miner in one hour has more than tripled since 1978. Surface mining is used to produce most of the coal in the because it is less expensive than underground mining. Surface mining can be used when the coal is buried less than 200 feet underground.
