Apparatus for supporting an explosive device

An apparatus for supporting an explosive device between a first surface and a second surface, the apparatus comprising:

• a base member comprising a base member aperture to provide a passage to a base chamber of the base member;
• one or more support members telescopically receivable through the base member aperture and into the base chamber, wherein the one or more support members support the explosive device;
• a fluid aperture to allow pressurised fluid into the base chamber to force the one or more support members towards an extended configuration such that at least part of the one or more support members are telescopically extended out of the base chamber, such that the one or more support members, with the explosive device, extend towards the second surface such that the apparatus is propped between the first surface and the second surface, and wherein the explosive device supported by the one or more support members is positioned proximal to the second surface;
• a sealing element, wherein the sealing element forms a first seal between at least one of the support members and a wall of the base chamber to prevent or reduce leakage of pressurised fluid out of the base chamber;
• a valve associated with the fluid aperture, wherein the valve is configurable to inhibit flow of pressurised fluid out of the base chamber via the fluid aperture;
• and
• an interface at the base member, wherein the interface is selectively connectable to an interface head associated with a mining machine.
