Introduction to Tongmei Datang Tashan Coal Mine Co., Ltd.

Tashan Coal Mine started construction in February 2003 and produced coal on a trial basis in July 2006. It is currently the largest mine in China with the largest designed production capacity and an annual output of 15 million tons of coal. Two fully mechanized mining low-level top coal caving working faces have been formed, which have reached the domestic first-class level in terms of single wellhead output, unit output per working face, per capita efficiency, coal recovery rate, cost and profit rate, etc., and are modern high-yield and efficient mines.

On July 19, 2006, the first trial production of Tashan Coal Mine was successful, announcing the birth of a large-scale modern coal mine that represents the advanced level of China's coal industry in the 21st century. At the same time, eight supporting projects, including coal preparation plants, comprehensive resource utilization power plants, and dedicated railway lines, have been put into operation. On October 15, 2008, Tongmei Datang Tashan 2×600 MW pithead power plant was completed and started generating electricity; on December 18, 2008, Tongmei Datang, the world’s largest single-wellhead underground mine, with an annual output of 15 million tons of coal The Tashan Coal Mine and the coal preparation plant project with an annual output of 15 million tons of washed coal passed the national acceptance; on July 31, 2009, two projects with an annual output of 50,000 tons of kaolin and an annual output of 120 million sintered bricks were completed and put into production. The complete closure of the industrial chain has been achieved. In 2009, Tashan Park achieved an output value of 8.5 billion yuan, sales revenue of 4.5 billion yuan, and profits and taxes of nearly 3 billion yuan, ranking first in the mid-term evaluation of the province's 13 pilot circular economy parks. At the same time, Tashan Coal Mine built the first fully mechanized mining team with an annual output of 10 million tons in the development history of Tongmei Group that year, creating the "eight best" and fifteen records in the history of Tongmei Group. Eight The best: the fastest mine construction speed (3 years and 5 months), the highest working surface recovery rate (94.48), the highest per capita efficiency (21,250 tons/person.year), and the lowest energy consumption per ton of raw coal production (1.88 kg of standard coal/ tons), the lowest comprehensive energy consumption per 10,000 yuan output value (0.05 tons of standard coal per 10,000 yuan), the highest corporate environmental behavior evaluation level in Shanxi Province (the highest "green" behavior level among Shanxi Province levels), and the highest annual output of comprehensive mining (15 million tons/year), and the fastest moving of the fully mechanized mining working face (20 days); the fifteen records are: daily fully mechanized mining output (58,000 tons), monthly fully mechanized mining output (1,312,008 tons), fully mechanized mining unit output (10,389,943 tons) /year), daily production of clean coal (42,765 tons), daily washed raw coal (71,616 tons), monthly washed raw coal (1,549,353 tons), monthly clean coal transportation (808,545 tons), top coal recovery rate (93.14), Mining labor efficiency (299.09 tons/work), overall employee efficiency (98 tons/work), coal preparation efficiency (200.85 tons/work), tunnel consumption of 10,000 tons (4.585M/10,000 tons), sales revenue (4.422 billion yuan), Achieved profit (1.312 billion yuan, per capita profit of 1.64 million yuan), a national-level green mine (awarded "National-level Green Mine" by the Ministry of Land and Resources).

In 2010, Tashan Coal Mine delivered a perfect answer to the end of the “Eleventh Five-Year Plan”. All work achieved new successes, safety management continued to be stable, coal production grew steadily, and scientific and technological innovation achievements were remarkable. Outstanding results in operation and management. Engineering construction projects that are carried out simultaneously with production management are also progressing smoothly. 18,760 meters of roadway engineering in the third panel area have been completed, and the remaining amount of work for the first mining face to be put into production is 5,282 meters. It is expected that the first mining working face will be circled in mid-April 2011. In May, the system transformation and main fan operation in the third panel area will be completed by the end of June. With the stable installation and commissioning of the first mining face, the first mining face of the third panel area was put into operation on July 1; the key project Yanya Auxiliary Pingdong has started and will be put into use in July 2011. The reconstruction project of the compressed air system is about to be completed. Led by the Ministry of Science and Technology and mainly undertaken by the China Coal Research Institute and the Group Company, the national "Eleventh Five-Year Plan" science and technology support project "Ten-million-ton large mining height fully mechanized caving equipment and technology" project has been fully launched, and the 8105 experimental working face equipment has been launched The installation was completed and the industrial experiment phase began.
