The telescopic shelter 10, for providing refuge to miners, comprises a front 12, 14 and a rear 16, 18 module. Both have an inner 12, 16 and an outer 14, 18 layer, which are nested so the outer layer slides from a compact state to an extended state, with an airtight seal provided between the layers. An attachment portion 50, 52, which may be a flange with a seal, on the outer layers allows the modules to be attached when extended to form an airtight chamber 24. The front module has an airlock 34, which may have gas cylinders to purge it, a pressure release valve 44 and a toilet. The rear module may include batteries and a cooling system. Optionally a centre module 20 can be attached between the other modules. Also included is a method of constructing the shelter.
