[0002] In mine construction sites, temporary bathhouses are usually required to allow workers to clean themselves. However, the modification of the heating system in these bathhouses has always been a serious issue that mines need to address. The direct reasons are the limited space in the bathhouses, the inability to set the temperature too high, and the presence of a large amount of flammable materials such as clothing. The indirect reason is that in winter, the inability of miners' clothes to dry quickly seriously affects the health of mine workers.
