Electrical Shot Firing in Mines (With Diagram)

In Fig. 17.4. a schematic diagram is shown. Here we see that a resistance check circuit is provided to enable the complete external circuit to be tested prior to firing. This consists of a transistor circuit and is fed directly from the battery. Rotating the firing in an anti-clockwise direction causes SW 1 to be switched into the No. 2 position.
