Ensham (Underground) coal mine Report | Wood Mackenzie

May 27, 2019 · Ensham (Underground) is located in the southern Bowen Basin. Ensham's surface mine used to be one of Queensland's largest thermal coal exporters, with marketable production in excess of 8 Mtpa in 2005. But output from the surface mine decreased significantly since then because of rising costs associated with a high strip ratio.

Advantages & Disadvantages of Coal Gasification | Sciencing

By the 1930s, underground coal gasification (UCG) also took root. UCG in particular used a method of circulating gasification agents like air, oxygen and water into the coal itself. This process converted coal to useful gases from the coal itself without needing to mine the material.
