Tangkou Coal Mine is the last pair of modern mines built by Zibo Mining Group in northern Jining, which was put into operation last year. The total investment of the mine is 65.438+0.5 billion yuan, the designed annual production capacity is 3 million tons, and the depths of the main shaft, auxiliary shaft and air shaft all exceed 1000 meters, and they are distributed in the same square, which is the only one in Asia.
At the beginning of the construction of the mine, Zi Mining Group put forward the slogan of "making science and technology a booster" to push Tangkou Coal Mine into the first phalanx in China. In the process of building wells, they achieved good results of "one broke the world record and five set the national record", which wrote a miracle in the history of mine construction in China. Through the implementation of the "thousand-meter deep well construction technology", the overall construction of Tangkou Coal Mine is 26 months ahead of the scheduled construction period, with an additional sales income of 265,438+600 million yuan and a profit and tax of 720 million yuan. This technology won the second prize of national scientific and technological progress last year.
Compared with huge economic benefits, this technology has far-reaching social benefits. At present, it has been widely used in deep well construction in Huainan, Zaozhuang, Juye and other mining areas, which has produced great economic benefits and has great social and practical significance for deep well construction and the development of new large coal bases in China, especially for the stable development of East China, which is short of coal resources.
Tangkou Coal Mine started the project of all-staff innovation and efficiency creation around improving efficiency and benefit. The mine has set up a scientific and technological innovation research team to carry out research on major issues that restrict production and improve efficiency; Cooperate with China University of Mining and Technology to study the rapid excavation technology of rock roadway, and save the cost per meter of roadway from 200 yuan to 400 yuan; At present, we are cooperating with Jining Majie Company to further optimize the supporting parameters and technology of deformed roadway. After the implementation of this technology, the cost per meter of roadway can be reduced by about 1.200 yuan.
At the same time, the mine has set up scientific and technological innovation groups in each team. According to the actual production and operation, each team sets the project name, technical indicators, completion time and responsible person, and actively advocates innovation. Tangkou Coal Mine also requires every employee to complete a small innovation or at least adopt a rationalization proposal during the year to encourage everyone to have innovative projects. They also set up innovation awards to reward innovation teams and innovators according to innovation achievements, so as to stimulate everyone's enthusiasm for innovation. Only this year, 73 team innovations have been completed, and employees' rationalization suggestions 152 have been adopted, resulting in accumulated benefits of120,000 yuan.
Safety is a major event in coal mines. Tangkou Coal Mine regards improving safety guarantee ability as the key point of scientific and technological innovation, and has built an underground safety monitoring system, which has realized remote digital monitoring of all underground tunneling faces. The mine installed and used PHS communication system, covering the whole underground and ground industrial square, which provided convenience for mine production scheduling and command. Tangkou Coal Mine has also cooperated with China University of Mining and Technology, Academy of Coal Sciences and other universities to carry out research on projects such as cooling technology of 1,000-meter deep well, law of gas occurrence and emission in underground coal seam, ground pressure in deep well, coal seam water injection, etc., which greatly improved the mine's intrinsic safety guarantee capability.
