Zhaolou Coal Mine Coal Reserve Report

Coal mining, and in particular underground coal mining, is carried out in an environment where not all events are predictable. Whilst an effective management team can, firstly, identify the known risks, and secondly, take measures to manage and mitigate these risks, there is still the possibility for unexpected and unpredictable events to occur.

Glossary of Mining Terms

Strip mine - An open-pit mine, usually a coal mine, operated by removing overburden, excavating the coal seam, then returning the overburden. Sub-bituminous - A black coal, intermediate between lignite and bituminous. Sublevel - A level or working horizon in a mine between main working levels.

Coal and the environment

 · Effects of coal mining. Surface mines (sometimes called strip mines) were the source of about 62% of the coal mined in the United States in 2019. These mining operations remove the soil and rock above coal deposits, or seams. The largest surface mines in the United States are in Wyoming''s Powder River Basin, where coal deposits are close to the ...

Exploration | Introduction | underground COAL

Coal bed methane production is becoming more common, whether primarily for gas production or to remove gas prior to mining. If these holes can be used for exploration without compromising their use for gas drainage then savings can be obtained.

Consistency in Coal Resource reporting
