【Abstract】 With the increasing of the exploiting depth in a mine,the temperature in it becomes higher and higher.In view of the high-temperature occurring at the dead-end of a tunnel,an idea of insulating heat with double-deck air layers was put forward,and the heat-insulating mechanism of the double-deck air layers briefly described in this paper.更多还原
