| Abstract: | In the design and construction of high slope,the presplitting blasting is employed to reach the effect of vibration relieving in the case when the blasting speed should be controlled to some extent.The present paper,regarding a quarrying engineering operated at a certain dock,discussed the parameters of presplitting holes,the buffer holes together with determination and selection of the charging structure,ignition networks.These were followed by the discussion of the requirements,the attending points in the construction,and the acceptance standard of open slope. |
