The Recent Technological Development of Intelligent Mining
China’s coal mining technology is still advancing toward the level of the mining technology in Australia, Germany, and the United States. Usage of this system led to an increase in production capacity of 15%, Development of intelligent technology and equipment in fully-mechanized coal mining face. J China Coal Soc, 39 (8) (2014), ppIn 2021, the national average sales price of coal (excluding anthracite) at coal mines was $31.99 per short ton, and the average delivered price of all coal delivered to the electric power sector was $37.32 per short ton. The difference is an average transportation cost of $5.33 per short ton, or about 14% of the average delivered price to theCoal explained U.S. Energy Information Administration (EIA)

Prices and costs Coal 2020 Analysis IEA
Prices. Coal prices vary by region as well as by grade and quality. The price rebound starting in 2016 ended in 2018, moving in a downward trend in 2019. After stabilisation of prices in the beginning of 2020, Covid-related demand suppression pushed prices down. FOB prices for thermal coal with a calorific value (CV) of 6 000 kcal/kg which hadThe system is essentially a serial process, and the cooperation between the pieces of equipment will seriously affect the performance of the system, so it is particularly important to study the optimization of coal mining truck flow in open-pit mines. 2.

Understanding the salinity issue of coal mine spoils in the
The coal mining process uses a large quantity of water to wash coal and equipment and suppress dust. For example, in New South Wales, mining operations consumed approximately 6.6 × 10 10 liters of water, and about 60 % was used by coal mining (NSW Minerals council 2011). Meanwhile, rainfall can be a significant input of water.During the “golden decade” (2001–2011) of the coal industry in China, rent-seeking increased in coal mine safety supervision alongside significant improvements in coal mine safety status and(PDF) Productivity Improvement In Underground Coal Mines
