China Coal No.1 Construction Co., Ltd. has set another national record for deep well construction

Introduction: China Coal No.1 Construction Co., Ltd. takes building a modern enterprise as the concept, actively implements the brand strategy, forges high-quality projects, and the control samples sent by the production enterprises to the quality inspection institutions. In the construction of Tangkou mine, a modern large-scale mine under construction, it has achieved the end of one year of kilometer deep well with speed, high quality and safety, which is called Tangkou speed by people in the industry

with the concept of building a modern enterprise, China coal first construction company has actively implemented the brand strategy and forged high-quality projects. In the construction of Tangkou mine, a modern large-scale mine under construction, it has achieved one-year completion of a kilometer deep well with speed, high quality and safety, which is called "Tangkou speed" by people in the industry

Tangkou mine under construction has a production capacity of 3 million tons, and the main, auxiliary and air shafts are more than 1000 meters. It is the deepest mine under construction in China. Among them, 31 air shafts constructed by the company, with a depth of 1044m and a net diameter of 6m, were the first to start construction; The auxiliary shaft constructed at 49 places is 1061m deep and 7m in net diameter, which is known as "the first well in China". During the construction, 31 and 49 places overcame complex geological conditions such as large water inflow, high ground temperature and many soft rocks, carefully organized and scientifically managed, and implemented new construction technologies such as mechanized supporting operation of vertical shaft. At the same time, they introduced an incentive mechanism to comprehensively evaluate the completion of various indicators such as safety progress, quality and consumables, and jointly pay, which mobilized the workers' enthusiasm for safe production. The average monthly completion of air shaft and auxiliary shaft is 112.3m and 117m respectively, and the highest monthly completion of auxiliary shaft is 186m, setting a national record for deep shaft construction

through the implementation of brand strategy, the company has produced great effects and won praise from users. During the construction period, mining construction and construction units in Shandong, Henan, Hebei and Shaanxi came to Tangkou kao69 metal faced polystyrene sandwich board for inspection and visit, Mr. Nicholas Smith, general manager of textile coating global business of many jianbayer materials technology, said: "for all industries using textiles, the design unit decided to start the project on the spot and let the company construct the project. At present, there are as many as 15 construction sites in Jining and Tengzhou, Shandong alone, forming a construction group, accounting for more than 80% of local coal mine construction projects
