发明名称 Underground mine personnel doors
摘要 A mine door for use in underground mining includes a door panel hingedly mounted to a door frame. A substantially noncombustible seal member is interposed between the door frame and the door panel and is preferably comprised of a flexible outer sleeve housing a resilient metal mesh core. The door panel is latched to the door frame by a latching device that ensures that the seal member is maintained in a substantially compressed condition.
