Underground mining, sometimes called deep mining, is a process that retrieves coal from deep below the Earth's surface—sometimes as far as 300 meters (1,000 feet). Miners travel by elevator down a mine shaft to reach the depths of the mine, and operate heavy machinery that extracts the coal and moves it above ground.

One is coal direct liquefaction technology and the other method can be divided into two processes. The first process is coal gasification where the coal is turned into a gas phase called syngas and the second process is producing multifarious organics including methanol from coalbased syngas (Zhao and Kelly, 2007).

The selected production process is typically based on a number of the following factors: types of available, cost of feedstocks, and the desired syngas product composition. The syngas composition is commonly referred to in terms of H2/CO ratio, which is simply the moles of hydrogen divided by the moles of carbon monoxide.

1 Introduction. Synthesis gas (syngas) production is the cornerstone of many industries. This H2 /CO mixture is mainly produced from gasification (coal, heavy hydrocarbons) or reforming (light hydrocarbons). Steam, oxygen, carbon dioxide or mixtures of them act as reforming agents and react with the carbon source at high temperatures.

Syngas is an essential platform chemical for producing chemicals and fuels, whose market volume is expected to grow strongly. Today, syngas is mainly produced from fossil resources and thus emits large amounts of greenhouse gases (GHGs). The GHG emissions of syngas can be reduced by alternative feedstocks such as biomass, CO2, and steel mill offgases (mill gas). However, since previous ...

It is the process of producing syngas, a mixture consisting carbon monoxide (CO), hydrogen (H2), carbon dioxide (CO2), natural gas (CH4), and water vapour (H2O). During gasification, coal is blown with oxygen and steam while also being heated under high pressure. During the reaction, oxygen and water molecules oxidize the coal and produce syngas.

The process was later applied industrially to generate heat and power. In the 1930s, synthetic fuel production from coal became important during World War II as crude oil supplies were interrupted. In the 1970s, during the energy crisis, interest in gasification escalated as a way to generate synthetic natural gas from coal.
