  • Underground coal gasifiion (UCG) is an industrial process which converts coal into product gas. UCG is an insitu gasifiion process, carried out in nonmined coal seams using injection of oxidants and steam. The product gas is brought to the surface through production wells drilled from the surface. The predominant product gases are methane, hydrogen, carbon monoxide and carbon dioxide.

  • underground mining systems Flexibility is an integral part of mine planning and design. Here, flexible alternatives are evaluated and contingency plans are built where this is judged to be necessary. Examples of specific factors governing flexibility identified in planning and design of underground hard rock mines (Kazakidis, 2001) include:
