| Abstract: | Ditching blasting differs from common bench blasting, but it has its specialty and complexity. While in the course of blasting design and construction, the rock geology characteristic and the environment should be sufficiently realized, and the scheme of blasting and valid protection measure should be established. According to the characteristic of Zhangfang emergency water engineering of Beijing, this paper introduces the principle of ditching blasting and the scheme of blasting construction. Relative technique measures of ditching controlling blasting are put forward, such as the pattern of hole disposal, structure of stage charge, techniques of millisecond blasting, measures of reducing vibration and controlling blasting flying rock. The methods above are used in practice engineering and ideal achievement is obtained. |
