Abstract: In order to solve the poor blasting smoke and dust control effect problems of the water stemming, with a certain additives to the water stemming, a new water stemming was researched and developed. The moisture test, the surface tension test and the toxicity reduction test was conducted on the main composition of the additives.The test results showed that with certain additives added, the moisture speed could be improved, the surface tension of the liquid would be reduced and the ni tric oxides and other toxic and harmful material could be removed.The adding plan and manufacturing of additives to water stemming was designed and the comparison test was conducted.The results showed that with the additives added, the blasting total dust control rate of the water stemming improved over 40%.
