Abstract

The conveyor comprises an inner hose (2) for transporting coal by pneumatic pressure and an outer hose (3) separated from the inner hose by a sealed intermediate compartment (8) which is pressuretight at atmospheric pressure. The inner and/or outer hose contains a core for increasing its mechanical strength. A means is provided for measuring the pressure inside the compartment and emitting a warning signal if a change in this pressure exceeds a threshold value.
