Apr 04, 2017 Between 1994 and 2005, eight miners were injured by exposure to blasting fumes. Surface blasting breaks up rock and frequently throws rock away from the blast site. Mine workers may be killed or injured by rock thrown by a blast. The blaster who designs a blast determines how far rock from the blast is expected to go.

An Analysis Of Burn Cut Pull Optimization Through

In underground blasting, the pull of the initial cut is the limiting factor for the success of the rest of the round. By improving the pull of the first cut, a critical step is made towards improving the entire round. This project attempted to optimize a burn cuts effective pull by varying the depths of the relief holes in the burn, and then

Blast Vibration Studies In Surface Mines

Blasting is very important process for mining operation and a lot of explosive is used for this purpose. The blasting process and usage of explosives, however, remain a potential source of numerous human and environmental hazards. Various studies indicate that fragmentation accounts for only 20-30% of the total amount of explosive energy used. ...

What Is A Copper Slag With Pictures Infobloom

Copper slag is a by-product created during the copper smelting and refining process. As refineries draw metal out of copper ore, they produce a large volume of non-metallic dust, soot, and rock. Collectively, these materials make up slag, which can be used for a surprising number of applications in the building and industrial fields.
