Known types of Blasting Caps used in Bisbee’s underground mines

 

 

     These are the known types of blasting caps used in Bisbee’s underground mines.  Bisbee almost exclusively, used fire  fuse caps underground until end of operations.  The fear of stray electricity  underground prevent widespread use of electric blasting caps. Only one  blasting cap box was found in the leaser areas. Electric caps were used in other areas but the types are unknown. 

 Different sizes of fire fuse blasting caps from top to bottom No.8,  No.6, No.3
