The company independently built and built six large and extra-large mines, built or expanded 10 large coal washing plant, and 1993 created the best construction in Asia to hoist the mixed well derrick of Lujiatuo Mine in Kailuan with a total weight of 747 tons. In 2005, the main shaft derrick of Anhui Huainan butyl coal mine was created with an integral lifting weight of 865 tons. In 2007, the derrick of Anhui Huainan Zhuji abandoned well reached the first-class level in the industry with an integral lifting weight of 9 15 tons. The drainage project of Niuerzhuang Mine in Fengfeng Mining Area set a new record for the fastest installation speed of similar projects in China, and the freezing project of main shaft and auxiliary shaft of butyl mine in Huainan Mining Group in Anhui Province set a new record for the shortest crossing time of freezing holes with a freezing depth of 565 meters in China. In 2005, the 2000m3 cooling tower project of Kailuan Power Plant won the highest quality award of China coal mine construction project-Sun Cup Award; The scientific and technological project "Research and application of rapid freezing technology for ultra-thick expansive clay in deep impact layer" won the top ten scientific and technological achievements award of the national coal industry in 2005; "Erection method of large box steel structure permanent derrick in sinking process" won the technical patent of China National Intellectual Property Administration.
