Underground mining, we also call deep mining. It is a process that extracts coal from deep below the Earth's surface—may be as far as 300meters. For coal mining, you need use many coal mining machines like the conveyor belt. This is a complicated process and you are better to find a professional team to build the coal mining plant.

Cogasification of coals, flotoconcentrates and RDF was performed on 3 g samples in an analytical state. Fourteen coal samples from the Upper Silesian Coal Basin were dried and ground to grains below mm and heated in an inert nitrogen atmosphere at a heating rate of 10 °C/min. until temperatures of 800 °C and 900 °C were reached.

Coalfired electricity generation is the process of making electric power from the energy (carbon) stored in coal. The process of converting coal into electricity has multiple steps: 1. A machine called a pulverizer (shown below) grinds coal into a fine powder. 2. The coal powder mixes with hot air, which helps it burn more efficiently.

In very simple terms, the process of converting ROM coal into marketable products is called coal preparation. Levels of cleaning Coal preparation results in at least two product streams, the clean coal product and the reject. Generally, five levels of preparation can be identified, each being an incremental level of cleaning over the previous one:

An integrated gasification combined cycle (IGCC) is a technology using a high pressure gasifier to turn coal and other carbon based fuels into pressurized gas—synthesis gas ().It can then remove impurities from the syngas prior to the electricity generation cycle. Some of these pollutants, such as sulfur, can be turned into reusable byproducts through the Claus process.
