On June 5438+ 10, 2009, the Sihe Mine Project undertaken by the company was selected as one of the "100 Classic Excellent Projects" for the 60th anniversary of the founding of New China, together with Tiananmen Square Complex, Three Gorges Water Control Project, Bird's Nest and Xichang Satellite Launch Base. Among the selected units, the top 80 are classic projects and the last 20 are excellent projects. Sihe project ranks first among the classic projects in coal mine construction. Four construction methods developed by the company, namely, mechanized rapid construction method of vertical shaft, mechanized rapid construction method of large-section inclined shaft production line, mechanized rapid construction method of frozen topsoil of vertical shaft and electromechanical installation method of vertical shaft, have been approved as national construction methods by the Ministry of Construction.
The company comprehensively innovates the management system and carefully cultivates the ace construction team. The mine construction technology, ability and level are in the leading position in the industry. In the aspect of vertical shaft construction, the company has two national construction methods, namely "vertical shaft mixed operation method" and "vertical shaft mechanized rapid construction method", and adopts the construction technology and method of "five big, two automatic, one deep and one centralized", as well as the organic matching of small excavators and central rotary rock grab, which has set a monthly completion of 2 16.9m for topsoil and 654,330 for bedrock in domestic vertical shaft construction. This well has set a new record for stable and high yield in China for eight consecutive months, exceeding 100 m (comprehensive monthly income 1 12 m), and officially entered the Shanghai Guinness Book of Records. In the construction of inclined shaft and roadway, the company has the first-class mechanized rapid construction method of inclined shaft in China, which has maintained the highest record of 309 meters of large-section excavation footage of inclined shaft in a single month. In installation engineering, have the ability to install large derrick and shaft equipment. The main shaft derrick (73.3 meters high and 853 tons) installed in Guqiao Coal Mine has set a new record for the installation height and weight of similar shafts. In terms of civil construction, slipform construction enjoys a high reputation. In Huating Coal Mine, Gansu Province, the 80-meter-high construction task of Asia's tallest and largest concrete well tower was completed. In terms of freezing construction, freezing technology and technology are at the leading level in China. In the freezing construction of Zhaogu Coal Mine in Henan Province, the freezing depth is 628 meters and the total installed capacity is 3630 kzl/h. In the two years from 2007 to now, with the joint efforts of the company's scientific and technological personnel, the company has made remarkable achievements in scientific and technological work and completed the scientific and technological investment of165.8 million yuan.
