A method of producing an assembly of a connector block () and a detonator () suitable for retaining at least one shock tube () adjacent to a percussion-actuation end () of the detonator, and to an assembly thus produced and a connector block therefor. The method comprising inserting a detonator into a connector block having a housing () provided with a bore (), positioning the detonator in the bore of the housing so that the percussion-actuation end of the detonator is positioned adjacent to a slot () for receiving the shock tubes; and fixing the detonator in the housing. The detonator is fixed in the housing by causing a body of material () to flow plastically into the recess in the detonator and to harden therein to form a locking element fixed to the housing, thereby preventing accidental movement of the detonator within the connector block.

Mining operations frequently involve the use of electric or electronic delay detonators in operative association with an explosive charge contained in a booster. Disclosed herein are connectors for connecting a signal transmission line to a detonator associated with a booster. In this way, the connectors, at least in preferred embodiments, allow the production of a substantially sealed booster assembly having a secure electrical connection to a signal transmission line. Also disclosed are methods of producing substantially sealed booster assemblies, and methods for their use in mining operations.
