Blasting in a mine generally occurs in two phases, primary blasting and secondary blasting. Primary blasting involves breaking down of in-situ rock in development and stoping as well as by drilling holes in rocks. Secondary blasting is performed to get rid of overburden. Drill and blast design is a key component of mine planning and management.

5. The blasting was initially 900-1000 feet from the wells. 6. The graphs of the water level monitoring (figs. 4 -6) show no noticeable ground -water level fluctuations that could be attributed to the blasting. The scale for observing changes was 1/100th of a foot. The blasting for the first 2 graphs occurred at about 15 minutes. Th e blasting
