H BLASTING IN SURFACE EXCAVATION - Mining and Blasting

In normal blasting all holes do not blast at the same time. Bench blasting is normally carried out as short delay blasting. The firing pattern has to be designed so that each blasthole has free breakage. The firing sequence of a chevron pattern can radically alter the drilled burden and spacing into the blasted or effective burden (Be)

Bodie History: Drilling Blasting in the Bodie Mines

Drilling and Blasting at Bodie . By. Michael H. Piatt . The only way to get ore out of the ground is to dig it out. The methods employed at Bodie had been adapted from eastern coal mining, then perfected on the Comstock during the 1860s. They remained essentially the same throughout the mining West.

Types of Underground Mining Method Comparison

The cost of mining is low because very little drilling and blasting, or timbering is required. The amount of development is small. A large output is possible. Disadvantages: The method is limited in application to low-grade ore of such character that it will cave and disintegrate. A large amount of ore becomes mixed with capping and lost.

Drill and Blast — A Necessary Evil Or? - AusIMM
