CONTROLLED BLASTING TECHNIQUE OFHIGH ROCK SLOPE ON ELECTRIFIED DOUBLE TRACK RAILWAY WITH MINIMUM DISTANCE BETWEEN CENTERSOF TRACKS |
| |
| Abstract: | Inaccordance with the rock blasting proceeded on high steep slope of electrified doubletrack railway line with a distance of 4m between the centers of tracks,and combined withthe most difficult work site of the Zhu-Liu electrified double track railway,five kinds ofconstruction methods applied at work site are introduced emphatically,including theselection of adaptive blasting parameters and the distribution of blasting holes,as wellas the safety check and calculation for vibration and shock wave of blasting.Andtherefore,the safety,high efficiency and economical results are obtained in constructionworks. |
