China Develops Powerful Machine for Mining Ultra-Thin Coal Beds
10 Aug 2023
China has successfully developed a powerful coal seam shearer that can
extract ultra-thin coal beds, achieving record output levels. The machine,
developed by the Shanghai Research Institute of China Coal Technology and
Engineering Group Corporation (CCTEG), can be used on coal beds as thin as 1.3
meters. More than 70 of these machines have been deployed by major coal mining
companies in mainland China.
At a mine run by China’s National Energy Group, the
device achieved an unprecedented annual output of 2.6 million tonnes. The coal
seam shearer has a designed annual capacity of 3 million tonnes, three times
higher than similar machines. It is also more powerful, with an installed power
of 1,200 kilowatts, and can adjust its orientation and height.
China has been focusing on mining thinner coal
seams as locations with thicker coal deposits become depleted. This is driven
by the country’s need to sustain its coal consumption and ensure energy
security. However, while China has been making efforts to transition to cleaner
energy sources, coal mining activities will still need to be phased out in the
medium to long term to achieve its carbon neutrality goals.
Thin coal beds account for about 20% of China’s
total coal reserves, but they only yield about 7% of the nation’s coal output
due to poor mining conditions and low profitability. China is the world’s
largest producer and user of coal and remains heavily reliant on the fossil
fuel. Its dependence on coal has been driven by concerns about energy security,
the reliability of renewable energy sources, and its economic recovery.
China’s commitment to reducing emissions and
reaching carbon neutrality is crucial for global efforts to tackle the climate
crisis. However, the country’s coal demand continues to grow, with an estimated
3.5% increase expected this year. Efforts to secure coal supply and low prices
have resulted in a glut of the resource, which could impact China’s emissions
reduction commitments. President Xi Jinping has emphasized that China’s
commitments to reducing emissions and achieving carbon neutrality remain
steadfast.
