| Abstract: | The fact that no competitive mechanism of the survival of the fittest is operational in civil blasting industry has caused its development to be of obvious crude nature,and studies in this paper have found that the need for civil blasting tends to rise in this current century,and furthermore spurs investment and capacity extension in the relevant enterprises,resulting in a congestion in the way in gaining the profit which relies merely on the expansion of production capacity.But the problem is that under the situation that the increasing need from civil blasting market is limited,the transformation of developing ideas and ways of civil blasting should be considered,and will the one faced in the development of civil blasting industry in future. |
