Question

Hello dudes its time to get 50 points
Question- tell production of coal?

Answer 1

Coal can be extracted from the earth either by surface mining or underground mining. Once coal has been extracted, it can be used directly (for heating and industrial processes) or to fuel power plants for electricity. If coal is less than 61 meters (200 feet) underground, it can be extracted through surface mining.

by the way this question is for 5 points

Answer 2

Coal is a combustible black or brownish-black sedimentary rock, formed as rock stratacalled coal seams. Coal is mostly carbon with variable amounts of other elements; chiefly hydrogen, sulfur, oxygen, and nitrogen.[1] Coal is formed if dead plant matter decays into peat and over millions of years the heat and pressure of deep burial converts the peat into coal.[2]

As a fossil fuel burned for heat coal supplies about a quarter of the world's primary energyand is the largest source of energy for the generation of electricity.[3] Some iron and steel making and other industrial processes burn coal.

The extraction and use of coal causes many premature deaths and much illness.[4] Coal damages the environment; including by climate change as it is the largest anthropogenic source of carbon dioxide, 14 Gtin 2016[5] which is 40% of the total fossil fuel emissions.[6] As part of the worldwide energy transition many countries have stopped using or use less coal.

The largest consumer and importer of coal is China. And China mines almost half the world's coal, followed by India with about a tenth. Australia accounts for about a third of world coal exports followed by Indonesia and Russia.[7]
