Abstract:

A pre-packaged explosive charge of the type made up of modules having a threaded male coupling end and a threaded female coupling end is loaded into a bore hole by use of a plug fitting threadably attachable to the uppermost charge module. The fitting is constructed so that the torque required for disconnection of the fitting from the module is substantially less than the torque required to separate one module from another.
