ABSTRACT:
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.
