Abstract

An inflatable borehole plug comprising an inflatable fluid tight bag with a storage container containing an inflation fluid in a compressed state located within the fluid tight bag. The storage container has a first actuator and a second actuator located at opposite ends thereof to initiate release of inflation fluid and hence effect expansion of the fluid tight bag. Choice of the vertical orientation of the first and second actuators and of which or both are activated provides differing rates of release of the inflation fluid and corresponding different rates of inflation of the fluid tight bag.

Abstract

An explosives container comprising a flexible inner bag within a flexible outer bag, the outer bag comprising a first end and a second end and a booster compartment located on an external surface of the outer bag, adjacent the second end. An explosive composition can be located within the inner bag and, in use, the booster compartment contains an explosive booster and serves to maintain the explosive booster in close contact with the explosives composition. The explosives container further comprises an elongate sheath extending substantially between the first end and the second end of the outer bag and serving to house and protect a detonator cord from damage or dislodgement.
