An estimate for world coal production in the long run would be helpful for developing policies for alternative energy sources and for climate change This production has often been estimated from reserves that are calculated from measurements of coal seams We show that where the estimates based on reserves can be tested in mature coal regions, they have been too high, and that more accurate estimates can be made by curve fits to the production

The Oil Drum | The Coal Question, Revisited

I read "Estimating LongTerm World Coal Production with Logit and Probit Transforms" earlier and think the Logit and Probit transform approach is an advancement over Hubbert Linearization It looks similar to what Sam Foucher did with the Hybrid Shock Model Although no doubt better than HL, which both Rapier and I have shown dissatisfaction with, I would prefer that we think about depletion and a

China China is the world’s largest coal producer In 2017, China produced 3,523 million metric tons of coal (1,747 million tons of oil equivalent), accounting for 46 percent of the world coal production (in term of metric tons) China’s coal production peaked in 2013 at 3,974 million metric tons

Imminence of peak in US coal production and overestimation

The importance of coal to iron and steel production is even larger on the global scale, with 70% of the world’s production requiring coke (WCA, 2014) A decrease in the supply of metallurgical coal for metal production would have as large of an impact to society and the economy as would a decrease in electrical production from coal

The 7th Coal Buyers and Producers Meeting

Assuming annual production rate of 485 million tons (the original coal output target this year), the country's coal reserves can last for 76 years Realized coal production in 2018 was 528 million tons, far above the indicative target of 485 million tons In 2019, the government sets coal production target at 490 million tons, of which 128 million tons will be allocated for the domestic market particularly for coal

Coal and lignite Production Data | World Coal Production

After two years of growth, global coal production remained stable in 2019, as slowing electricity consumption reduced coal demand In China, the largest coal producer (47% of the global output), production grew by 4% for the third year in a row, in line with the continuing supplyside structural reform Coal production also increased slightly in Australia and accelerated in South Africa despite declining world
