Tongmei Group embarks on a new journey of high-quality development

Seventy is magnificent, and seventy changes have taken place. With the progress of new China, the same coal group has gone through 70 glorious years.

70 years, Tongshan Coal Group has experienced such important historical stages as comprehensive recovery, rapid ascent, wandering for improvement, adjustment, reorganization and reform and development. The scale of the enterprise is growing and its comprehensive strength is increasing. It has grown from a few simple mines, 3,000 workers and workers at the beginning of the establishment of the enterprise, with a total industrial output value of 1.44 million yuan and an annual output of 80,000 tons of coal into the world's top 500 enterprises and the whole country. One of the 100 million ton power coal group, the super large state-owned modern energy group, which is dominated by six major industries: coal, power, coal chemical industry, finance, cultural tourism and logistics. In 2018, the total assets of Tongmei Group amounted to 350.3 billion yuan, the sales revenue was 176.6 billion yuan, the coal output reached 137 million tons, and the installed capacity of electricity reached 170.85 million kilowatts. On August 30, 1949, Datong Mining Bureau, the predecessor of Tongtong Coal Group, was formally established. At that time, the devastated mine just returned to the hands of the people. The material was extremely scarce, the life was extremely hard and the equipment was extremely backward. 3000 miners were on the ruins, pulling shoulders, repairing the derricks, installing equipment, resuming transportation and starting production, providing the new China with urgently needed energy and strongly supporting the country's economic construction.

According to the data, the mining, excavation, transportation, lifting, ventilation and other production links of Datong Mining Bureau at that time still depended on the old equipment and followed the old production mode. With a series of production reforms, such as the test and popularization of single longwall mining method, the creation of double-channel circular tunneling operation method and the promotion of comprehensive chart and regular circular management method, the coal production of Datong Mining Bureau has broken through the inherent mode and developed rapidly. In 1952, the No. 6 well of the Datong Mining Bureau, Zhuang Zhuang coal mine, was selected for the first time to make coal and coal loading mechanized. The first generation of shearers used in the coal industry after the founding of new China was realized by the use of the coal mine in the coal mine of the Tang Dynasty, which was made by the system of 1 tons of coal. Especially from 1954 to 1957, when Datong Mining Bureau rebuilt and expanded the mine, the annual output of raw coal increased from 2.48 million tons in 1952 to 5.567 million tons.

In 1961, in order to change the difficult economic situation caused by natural disasters and oppression by international forces, the State Council formulated the eight-character policy of "adjusting, consolidating, enriching and improving the national economy". According to the instructions of provincial and municipal committees, Datong Mining Bureau has carried out expansion and reproduction transformation, ushering in the second upsurge of entrepreneurship. During the Second Five-Year Plan period, Datong Mining Bureau completed four new wells and carried out comprehensive renovation of two mines. The total design capacity reached 5.41 million tons, of which 2.55 million tons were new wells and 2.86 million tons were old wells. During the period, Datong Mining Bureau actively renovated and reformed the existing equipment, which promoted the development of mechanization of shearers. In 1965, the first domestic shallow-cut combined mining unit of Datong Mining Bureau was put into trial production in Tongjialiang No. 9 single longwall working face, marking a new development period of mechanized mining technology of Datong Mining Bureau. In that year, 9.4 million tons of raw coal were produced. During the 10 years from 1966 to 1975, Datong Mining Bureau successively extended, expanded and rebuilt the mine. After reconstruction and expansion, the overall well pattern has been expanded accordingly. At the same time, Datong Mining Bureau has started to set up fully mechanized mining equipment, which has made a great step forward in the level of mechanization of coal mining. The new stage of fully mechanized coal mining has been transformed from long-term manual and semi-mechanized heavy physical mining. In 1975, the raw coal output of Datong Mining Bureau reached 18.039 million tons, a net increase of 8.91 million tons compared with 1965, with a growth rate of 91.2%.

This conference opened the door of decades of dusty decades, made a major policy decision of China's reform and opening up, and established the basic national policy centered on economic construction. This spring breeze of reform and opening up has begun to revive China's land. Shortly after the closing of the Third Plenary Session of the Eleventh Central Committee of the Communist Party of China, the Datong Mining Bureau dispatched a study and exchange group to study the advanced comprehensive mechanized coal mining technology in Japan, which provided an important guarantee for the realization of mechanized coal mining in the future.

With the deepening of "importing, absorbing and digesting" advanced mining equipment, the role of fully mechanized mining equipment in Datong Mining Bureau is becoming more and more obvious, and the output is increasing year by year.

In 1979, the output of Digging Gold Bay reached 3.29 million tons, making it the highest output mine of Datong Mining Bureau. At the same time, the output of coal in six mines, Meiyukou Mine, Yanya Mine and Jinhuagong Mine, has doubled. In this year, the coal output of Datong Mining Bureau rose rapidly to 24 million tons, ranking first in the national coal industry. From the time to 1985, without adding new wells, the Datong Mining Bureau produced 30 million tons of coal, becoming the largest coal production base in China at that time, making an important contribution to national economic development and energy supply in the early stage of reform and opening-up. With the great development of national economy, Datong Mining Bureau keeps removing the old and innovating. Since 1985, the former Ministry of Coal has implemented the "general contract of input and output" for the unified distribution coal mines with better national benefits. Datong Mining Bureau has contracted out more than 40 units per ton of coal wages and 215 mining teams in 13 production mines in various forms. The economic system of Datong Mining Bureau has gradually changed from single reform to multi-level and omni-directional reform.
