A booster explosive (10) is comprised of assembled components comprising a canister body (12, 112) having a fuse tunnel (22) formed integrally therewith and a separate cap well (14, 114) mounted within the canister body (12, 112) which is filled with a solid cast explosive (34). The connector end (14c, 114c, 214c) of cap well (14, 114) is configured to engage cap well mounting fixture (28, 128) disposed within the canister body (12, 112). Cap well mounting fixture (28, 128) has a flexible and resilient crown-shaped locking member (28a, 128a) formed integrally therewith and is otherwise configured to positively retain a detonator (16, 116) within the cap well (14, 114). More than one cap well (214a, 214b, 214a′, 214b′) and more than one fuse tunnel (222a, 222b, 222a′, 222b′) may be provided in the canister body (212, 212′). |

1. Components for a canister assembly for a cast booster explosive, the components comprising a canister body defining an interior of the body and, separate from the canister body, a cap well:
(a) the canister body having (i) a wall defining an interior of the canister body, (ii) a canister base closing one end of the canister body, (iii) a fuse tunnel open at both ends thereof and extending along the length of the canister body, (iv) a cap well mounting fixture open to passage of a detonator therethrough, and (v) a locking member disposed at the mounting fixture and configured to retain a detonator within the cap well; and (b) the cap well being closed at one end and open at its opposite connector end, and being configured to have its connector end seated on the cap well mounting fixture, and to receive and enclose such detonator within the cap well to isolate such detonator from the interior of the canister body. |
