Mining in focus Not only do poor blasting practices erode mines’ financial bottom lines — they are also bad for the environment, writes Tony Rorke. S Blasting rock releases greenhouse gases, but poor blast results have a major negative impact on greenhouse gases. everal greenhouse gases are generated in the explosives chain; however, one is particularly dangerous.
