The temporary refuge chamber of Dongpang Mine is constructed by the way of roadway expansion and brick-concrete wall. The construction and transportation work is large, the construction time is long and the construction is difficult. In view of this problem, the mine independently designed and manufactured a new type of combined temporary refuge facilities, which not only solved a series of shortcomings of the existing brick-concrete temporary refuge chamber, but also realized the advantages of safe, fast, efficient and practical temporary refuge facilities, and improved the safety factor of the mine.
