| Abstract: | The comprehensive blasting technology which combines U kerr blasting with presplitting blasting and smooth blasting and millisecond delay blasting was studied. The principle of borehole arrangement based on wide hole spacing with small burden was discussed in detail. The method of blast-hole arrangement included such procedures as when the row spacing was determined the charging space was regulated based on landform and geology and the employed explosives, and based on the regulated row spacing, the charge quantity was finally determined by the stamping length. The paper also discussed the determination of the parameters for long hole-large area MS delay blasting,and the design method of ignition network by combining employment of electric detonator and conducting tube. Besides, the technologies of blasting safety correction were also discussed. |
| Keywords: | Cutting excavation Millisecond delay blasting U cutting Blast-hole arrangement |
