Brief Introduction of Liu Zhuang Coal Mine

Liu Zhuang Coal Mine is a super-large modern mine newly built by SDIC Xinji Energy Co., Ltd. in Fuyang. It is a national and provincial key construction project during the Tenth Five-Year Plan and an important part of the provincial "861" plan to build an energy base.

Liu Zhuang Coal Mine has been successively rated as "1 Major Classic and Excellent Projects" for the 6th anniversary of the founding of the People's Republic of China, "Luban Award" National Excellent Project, National May 1 Labor Award, National Super Safe and Efficient Mine of China Coal Industry Association, "Quality Investment Construction Project" of China Investment Association, First-class Safe and Efficient Mine of China Coal Industry Association, Anhui Advanced Collective, Anhui Quality Award Enterprise, and Anhui Advanced Collective of the Tenth Five-Year Development and Innovation Project of Millions of Workers.

Liu Zhuang Coal Mine has a designed production capacity of 8 million tons/year. Construction started in early 23 and trial production was completed on October 16th, 26. The planned investment in the mine is 2.8 billion yuan, and more than 2.6 billion yuan has been completed at present. In the process of shaft construction in Liu Zhuang Coal Mine, the monthly footage records of similar shafts in East China and China have been refreshed for many times, and the domestic advanced level of 8-meter-deep shaft has been created. Among them, it took less than 1 months for the intake and return shafts in the western mine, and all the two shafts were in the end. The monthly footage of the shafts exceeded 1 meters continuously for many times, respectively refreshing the frozen soil sinking and bedrock excavation of similar shafts in the "Huaibei" area. It takes only 35.5 days to freeze the circle in the 41m freezing depth of the return air shaft in the west area, which is the shortest record of the same kind of shaft freezing circle in China. Liu Zhuang Coal Mine took the lead in adopting the three parallel construction technologies of "injection, freezing and drilling" in China, and the project won the first prize of Anhui Science and Technology Progress in 25. All six shafts have been laid out in the mine construction. At present, the underground roadway construction is under way. The first mining interview production is progressing smoothly, and the total footage of the roadway has reached more than 2, meters. Underground ventilation, transportation, drainage, communication, power supply and other systems have been formed. The ground construction of Liu Zhuang Coal Mine has been promoted simultaneously. The tower of the first main shaft in Asia with a design height of 9.8 meters and the coal preparation plant supporting the mine construction have been completed and put into use. The feasibility study report of the first phase (2*6MW) project of Liu Zhuang Power Plant under design has passed the expert review of the State Electric Power Planning Institute.
