Abstract
|
|
|
In recent years, Korean nining industry showed the tendency to use more home-made dynamites and it was attributed to the improvement in quality of home-made dynamites.
In this study, to find out the possible changes in emission of noxious gases, it was confirmed that NO₂from home-made dynamite reached the lower level than that from Japanese product but higher level than that from American product. So we can see the NO₂concentration which is increased by incomplete combustion was lowered by the improvement of home-made dynamites.
